标准摘要
[中文适用范围]： 本文件规定了无侧限压缩试验的方法。 本文件适用于岩土工程勘察范围内压缩荷载作用下原状土、重压实土、重塑土或重构土的均质试件的无侧限抗压强度的测定。 该测试方法可用于估计土壤的不排水抗剪强度。 值得注意的是，在该测试期间不会阻止排水。 因此，不排水抗剪强度的估计值仅对低渗透性土壤有效，这些土壤在测试过程中表现出充分的不排水性。 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无侧限压缩试验的要求。 [外文原描述]： ISO 17892-7:2017 specifies a method for the unconfined compression test. ISO 17892-7:2017 is applicable to the determination of the unconfined compressive strength for a homogeneous specimen of undisturbed, re-compacted, remoulded or reconstituted soil under compression loading within the scope of geotechnical investigations. This test method is useful to estimate the undrained shear strength of soil. It is noted that drainage is not prevented during this test. The estimated value for undrained shear strength is, therefore, only valid for soils of low permeability, which behave sufficiently undrained during the test. NOTE This document fulfils the requirements of unconfined compression tests for geotechnical investigation and testing in accordance with EN 1997‑1 and EN 1997‑2.
