标准摘要
[中文适用范围]： 本文件规定了一种指数测试方法，用于确定土工合成材料与标准砂接触的摩擦特性，如 EN 196-1 中所述，即具有指定的密度和水分含量，在法向应力和恒定的位移速率下，使用直接剪切装置。 相同的测试程序可用于具有评估特定条件下的性能所需的密度和含水量的任何类型的土壤，或使用直接剪切装置在法向应力和恒定位移速率下使用另一种土工合成材料。 该程序还可用于测试土工合成屏障。 [外文原描述]： This document specifies an index test method to determine the friction characteristics of geosynthetics in contact with a standard sand as described in EN 196-1, i.e. with a specified density and moisture content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The same testing procedure can be used with any type of soil with the density and moisture content that are required to evaluate the performance under specific conditions or with another geosynthetic under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The procedure can also be used for testing geosynthetic barriers.
