ASTM D4945-00 桩的高应力动态试验的标准试验方法

This test method is used to provide data on strain or force and acceleration, velocity or displacement of a pile under impact force. The data are used to estimate the bearing capacity and the integrity of the pile, as well as hammer performance, pile stresses, and soil dynamics characteristics, such as soil damping coefficients and quake values. This test method is not intended to replace Test Method D 1143. 1.1 This test method covers the procedure for testing vertical or batter piles individually to determine the force and velocity response of the pile to an impact force applied axially by a pile driving hammer to the top of the pile. This test method is applicable to deep foundation units that function in a manner similar to foundation piles, regardless of their method of installation provided that they are receptive to high strain impact testing. 1.2 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific precautionary statement, see Note 5. Note 1--High-strain dynamic testing requires a strain at impact which is representative of a force in the pile having the same order of magnitude, or greater, than the ultimate capacity of the pile.Note 2--This standard method may be applied for high-strain dynamic testing of piles with the use of only force or strain transducers and/or acceleration, velocity or displacement transducers as long as the test results clearly state how the testing deviates from the standard.Note 3--A suitable follower may be required for testing cast-in-place concrete piles. This follower should have an impedance within 80 and 150% of that of the pile. However, additional caution and analysis may be required if the impedance is not within 10%. For mandrel driven piles, the mandrel may be instrumented in a similar way to a driven pile provided that the mandrel is constructed of a single member with no joints.

ASTM D6599-00(2008) 斜坡上梢捆建造的标准实施规程

Live fascines are used to provide erosion and sedimentation control by increasing infiltration, slowing or redirecting runoff, and trapping seed and sediments. The method provides shallow mechanical surface slope stabilization, and provides enhanced values through vegetative growth and additional shallow soil reinforcement through the development of the roots. The ability of live fascines to function properly depends on the quality and choice of the materials used to construct the live fascine, the means and methods of fabrication and installation, and proper consideration of site characteristics and time of year. For the live fascine to function completely, it is important that the live fascine develops suitable growth.1.1 This practice covers the material, fabrication and installation work to construct live fascines. 1.2 The values in this standard are in SI units and are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.3 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgement. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without considerations of a project''s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D1883-99 实验室压实泥土的CBR(加利福尼亚承载力比)的试验方法

1.1 This test method covers the determination of the CBR (California Bearing Ratio) of pavement subgrade, subbase, and base/course materials from laboratory compacted specimens. The test method is primarily intended for but not limited to, evaluating the strength of cohesive materials having maximum particle sizes less than 3/4 in. (19 mm). Note 1-The agency performing this test can be evaluated in accordance with Practice D3740. Not withstanding statements on precision and bias contained in this Standard: The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies which meet the criteria of Practice D3740 are generally considered capable of competent and objective testing. Users of this method are cautioned that compliance with Practice D3740 does not in itself assure reliable testing. Reliable testing depends on many factors; Practice D3740 provides a means of evaluating some of those factors. 1.2 When materials having maximum particle sizes greater than 3/4 in. (19 mm) are to be tested, this test method provides for modifying the gradation of the material so that the material used for tests all passes the 3/4-in. sieve while the total gravel (+No. 4 to 3 in.) fraction remains the same. While traditionally this method of specimen preparation has been used to avoid the error inherent in testing materials containing large particles in the CBR test apparatus, the modified material may have significantly different strength properties than the original material. However, a large experience base has developed using this test method for materials for which the gradation has been modified, and satisfactory design methods are in use based on the results of tests using this procedure. 1.3 Past practice has shown that CBR results for those materials having substantial percentages of particles retained on the No. 4 sieve are more variable than for finer materials. Consequently, more trials may be required for these materials to establish a reliable CBR. 1.4 This test method provides for the determination of the CBR of a material at optimum water content or a range of water content from a specified compaction test and a specified dry unit weight. The dry unit weight is usually given as a percentage of maximum dry unit weight from the compaction tests of Test Methods D698 or D1557. 1.5 The agency requesting the test shall specify the water content or range of water content and the dry unit weight for which the CBR is desired. 1.6 Unless specified otherwise by the requesting agency, or unless it has been shown to have no effect on test results for the material being tested, all specimens shall be soaked prior to penetration. 1.7 For the determination of CBR of field compacted materials, see Test Method D4429. 1.8 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents shown in parentheses may be approximate. 1.9 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4223-99(2006) 沥青固定土壤的试样制备的标准操作规程

This practice is intended for the preparation of standard specimens of soil-asphalt mixtures suitable for tests of Test Methods D 1559, D 1560, D 1561, D 4123, and other tests using specimens of the above dimensions. This practice is limited to only fine-grained soils as defined in 6.1. Note 18212;The quality of the results produced by this practice is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D 3740 are generally considered capable of competent and objective testing, sampling, inspection, and so forth. Users of this practice are cautioned that compliance with Practice D 3740 does not in itself ensure reliable results. Reliable results depend on many factors; Practice D 3740 provides a means of evaluating some of those factors.1.1 This practice covers the selection and proportioning of soils and emulsified or cutback asphalts and the fabrication of 4-in. (102-mm) diameter by 2.5-in. (54-mm) high test specimens.1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.1.3 The values stated in inch-pound units are to be regarded as standard, except as noted as follows. The values given in parentheses are mathematical conversions to SI units, and are provided for information only and are not considered standard.1.3.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In this system, the pound (lbf) represents a unit of force (weight), while the unit for mass is slugs.1.3.2 The slug unit of mass is almost never used in commercial practice (density, scales, balances, and so forth). Therefore, the standard unit for mass in this practice is either kilogram (kg) or gram (g), or both. Also, the equivalent inch-pound unit (slug) is not given.1.3.3 It is common practice in the engineering/construction profession in the United States to concurrently use pound to represent both a unit of mass (lbm) and of force (lbf). This use combines two separate system of units, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated in , this practice uses the gravitational system and does not present the slug unit for mass. However, the use of scales or balances recording pounds of mass (lbm) or the recording of density in lbm/ft3 shall not be regarded as nonconformance with this practice.1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project''s many unique aspects.

BS 5950-5:1998 建筑物钢铁架结构应用.冷成型薄式量规剖面设计实用规程.

This part of BS 5950 gives recommendations for the design of structural steelwork in buildings and allied structures using cold formed sections. It is primarily intended for steel sections of thickness up to 8 mm. Requirements for materials and construction are given in BS 5950-7. Sections may be either open or closed and should be made up of flat elements bounded either by free edges or by bends with included angles not exceeding 135°and internal radii not exceeding 5t where t is the material thickness. Closed sections may be made either: i) by joining together two previously formed open sections by continuous welding; ii) from a single flat strip, by forming the corners to make a box, and continuously welding the longitudinal joint.Welded cold formed hollow sections conforming to BS EN 10219 are not covered by this part of BS 5950. NOTE Cold formed products conforming to BS EN 10219 are the subject of amendments to BS 5950-1 and -2 which are in preparation.

ISO 4355:1998 结构设计基础 屋面雪荷载的确定

This International Standard specifies methods for the determination of snow load on roofs. It will serve as a basis for the development of national codes for the determination of snow load on roofs. National codes should supply statistical data of the ground snow load in the form of zone maps, tables or formulae. The shape coefficients presented in this International Standard are prepared for design application, and may thus be directly adopted for use in national codes, unless justification for other values is available. For examining the effect of the wind on the distribution of snow loads on roofs of unusual shapes or shapes not dealt with in this International Standard or in national standards, suitable models (e.g. tests carried out in a wind tunnel especially equipped for reproducing accumulation phenomena) may give significant results. The annexes describing methods for determining the characteristic snow load on the ground, exposure coefficient, thermal coefficient and loads on snow fences are for information only as a consequence of the limited amount of documentation and available scientific results. In some regions, single winters with unusual weather conditions may cause severe load conditions not taken into account by this International Standard. Specification of standard procedures and instrumentation for measurements is not dealt with in this International Standard.
