本文件规定了测定土工合成产品压缩蠕变性能的指数试验方法。试样承受正常压缩载荷或正常压缩载荷和剪切载荷的组合。 仅在正常荷载下的试验方法（见第5条）为标准方法。 施加法向荷载和剪切荷载组合的试验方法（见第6条）适用于对剪切破坏敏感的产品，即具有柱状或尖头结构的产品。 试验在干燥试样或浸入水中的试样上进行。当土工合成产品的任何部分包含亲水聚合物时，将试样浸入水中进行试验。

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.
