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 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。 1.3 该测试方法提供了一组用于执行一个或多个特定操作的指令。本文件不能取代教育或经验，应与专业判断一起使用。并非本惯例的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的许多独特方面的情况下应用本文件。 文字 “ 标准 ” 在本文件标题中，仅表示该文件已通过ASTM共识程序获得批准 . ====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 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. 1.3 This test method 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. The word “ Standard ” in the title of this document means only that the document has been approved through the ASTM consensus process . ====== 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.
