本文件规定了一种指数试验方法,以确定土工合成材料与EN 196-1中所述标准砂接触时的摩擦特性,即在正应力和恒定位移率下,使用直剪仪测定规定密度和含水量的土工合成材料的摩擦特性。相同的测试程序可用于任何类型的土壤,其密度和含水量是评估特定条件下性能所需的,或用于另一种土工合成材料,在正常应力和恒定位移率下,使用直剪仪。该程序也可用于测试土工合成屏障。
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.
