Standard Test Method for Unconfined Compressive Strength Index of Chemical-Grouted Soils 化学灌浆土壤无侧限抗压强度指数的标准试验方法
发布日期: 2002-11-10
1.1本试验方法包括使用应变控制施加试验荷载,测定化学灌浆土壤的短期无侧限抗压强度指数。 1.2以英寸-磅为单位的数值应视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全和健康实践,并确定监管限制的适用性。 ====意义和用途====== 本试验方法的目的是获得与其他试验值进行比较的值,以验证灌浆土壤成分中材料的均匀性或可控变量的影响。 该试验方法原则上与试验方法D 2166相似 ,但不用于确定设计中使用的强度参数。这些值更适合从长期三轴试验中获得。 笔记 1-本标准产生的结果的质量取决于执行该标准的人员的能力,以及所用设备和设施的适用性。符合实践D 3740标准的机构 通常认为能够胜任和客观的测试/采样/检查等。本标准的用户应注意遵守实施规程D 3740 本身并不能保证可靠的结果。可靠的结果取决于许多因素;实践D 3740 提供了一种评估其中一些因素的方法。
1.1 This test method covers the determination of the short-term unconfined compressive strength index of chemically grouted soils, using strain-controlled application of test load. 1.2 The values stated in inch-pound units are to be regarded as standard. 1.3 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. ====== Significance And Use ====== The purpose of this test method is to obtain values for comparison with other test values to verify uniformity of materials or the effects of controllable variables, in grout-soil compositions. This test method is similar, in principle, to Test Method D 2166 , but is not intended for determination of strength parameters to be used in design. Such values are more properly obtained from long-term triaxial tests. Note 1—The quality of the result produced by this standard 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/etc. Users of this standard are cautioned that compliance with Practice D 3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D 3740 provides a means of evaluating some of those factors.
