1.1本规程涵盖化学灌浆土壤样本的实验室制备，用于实验室试验，以确定设计强度参数。 注1-本规程可能不适用于凝胶时间短于用灌浆使试样饱和所需时间的灌浆混合物。 1.2试样用于无侧限和约束压缩试验中的强度和模量测定。 注2:试验方法D 4219和D 5202中描述了用于其他目的的试样的制备方法。 1.3本规程要求将灌浆注入已制作至所需密度的土壤样本中。 1.4所有观察值和计算值应符合实施规程D 6026中规定的有效数字和舍入准则。 1.4.1本标准中用于规定如何收集、计算或记录数据的方法与数据可用于设计或其他用途或两者的准确性没有直接关系。 如何应用使用本标准获得的结果超出了其范围。 1.5除非下文另有说明，否则以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.6 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，并确定监管要求的适用性。 1.7本规程提供了一套用于执行一个或多个特定操作的说明。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，也不应在不考虑许多独特方面的情况下应用本文件。本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.8本标准的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 ====意义和用途====== 当试验数据用于设计目的时，本规程的目的是制备化学灌浆土壤样本，用于无侧限或三轴压缩试验。 笔记 3-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 practice covers the laboratory preparation of chemically grouted soil specimens for use in laboratory tests to determine design strength parameters. Note 1—This practice may not be applicable to grout mixtures with gel times shorter than the time required to saturate the specimen with grout. 1.2 The specimens are intended for both strength and modulus determination in unconfined and confined compression testing. Note 2—Preparation methods for specimens to be used for other purposes are described in Test Methods D 4219 and D 5202. 1.3 This practice requires the injection of grout into soil specimens already fabricated to a desired density. 1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026. 1.4.1 The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in design or other uses, or both. How one applies the results obtained using this standard is beyond its scope. 1.5 The values stated in inch-pound units are to be regarded as standard, except as noted below. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard. 1.6 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 requirements prior to use. 1.7 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 projects 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. 1.8 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. ====== Significance And Use ====== The purpose of this practice is to prepare specimens of chemically grouted soils for testing in unconfined or triaxial compression, when the test data is to be used for design purposes. Note 3—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.
