标准摘要
[中文适用范围]： 本文件规定了测定土工合成材料产品压缩蠕变性能的指标测试方法。 测试样本要么承受正常压缩载荷，要么承受正常压缩载荷和剪切载荷的组合。 仅使用正常负载的测试方法（参见第 5 条）是标准方法。 施加组合法向载荷和剪切载荷的测试方法（参见第 6 条）适用于对剪切破坏敏感的产品，即具有柱状或尖状结构的产品。 测试在干燥样品或浸入水中的样品上进行。 当土工合成产品的任何部分含有亲水性聚合物时，应将样品浸入水中进行测试。 [外文原描述]： This document specifies index test methods for determining the compressive creep properties of geosynthetic products. The test specimens are subjected either to normal compressive loading or to a combination of normal compressive loading and shear loading. The test method with a normal load only (see Clause 5) is the standard method. The test method in which combined normal and shear loads are applied (see Clause 6) is intended for products that are sensitive to shear failure, i.e. which have a columnar or cuspated structure. The tests are carried out on dry specimens or on specimens immersed in water. The test is intended to be carried out with the specimen immersed in water when any part of the geosynthetic product contains a hydrophilic polymer.
