摘　　要：土工合成材料加筋土工程中 ,土工合成材料与填土的界面作用特性直接决定加筋土结构的内部稳定性 ,所以土工合成材料与填料的界面作用特性指标是最关键的技术指标。通过对粘土与聚丙烯土工带在不同含水量、剪切速率下进行不同法向荷载作用下的剪切试验 ,得出了高液限粘土与筋带之间的剪切特性 ,讨论了法向应力、剪切速率及含水量对界面剪切特性的影响 。In geopolymer reinforced soil structure, the behavior between the soil and geopolymer is very important to inner stabilization of reinforced soil structure, so the index between the soil and geopolymer is a crucial index. In this paper, systematic direct-shear tests in large direct-shear apparatus are carried out for the clay reinforced by geofabric under different normal stresses, shear rate and water content. Based on the test result, stress-strain relationship is studied. Some useful conclusions and opinions which can be used to make research and design are also presented.
