ISO 17892-7:2017规定了无侧限压缩试验的方法。 ISO 17892-7:2017适用于在岩土工程勘察范围内确定压缩荷载下未受干扰，再压实，重塑或再生土的均匀试样的无侧限抗压强度。 这种测试方法可用于估算土的不排水抗剪强度。值得注意的是在这个测试过程中不会阻止排水。因此，不排水剪切强度的估算值仅适用于低渗透性的土壤，其在测试过程中表现出足够的不排水。 注:本文件符合EN 1997-1和EN 1997-2中有关岩土工程勘察和试验的无侧限压缩试验的要求。

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.
