标准摘要
[中文适用范围]： 本文件规定了松散不排水三轴压缩试验的方法。 本文件适用于岩土工程勘察范围内压缩荷载下不排水三轴剪切强度的实验室测定。 圆柱形样本可以包括未扰动的、重新压实的、重塑的或重构的土壤，在不排水条件下经受各向同性应力，然后在不排水条件下剪切。 该测试可以确定剪切强度和总应力方面的应力-应变关系。 本文件不包括非标准程序，例如孔隙压力测量测试或过滤排水测试。 注：本文件满足根据 EN 1997-1 和 EN 1997-2 进行岩土勘察和测试的松散不排水三轴压缩试验的要求。 [外文原描述]： ISO 17892-8:2018 specifies a method for unconsolidated undrained triaxial compression tests. ISO 17892-8:2018 is applicable to the laboratory determination of undrained triaxial shear strength under compression loading within the scope of geotechnical investigations. The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic stress under undrained conditions and thereafter is sheared under undrained conditions. The test allows the determination of shear strength and stress-strain relationships in terms of total stresses. Non-standard procedures such as tests with the measurement of pore pressure or tests with filter drains are not covered in this document. NOTE This document fulfils the requirements of unconsolidated undrained triaxial compression tests for geotechnical investigation and testing in accordance with EN 1997‑1 and EN 1997‑2.
