摘    要:筋土之间的摩擦力是加筋土结构的一个重要设计参数.对三种不同粗糙度的土工合成材料与粘土在不同含水量、垂直压力下进行了直剪试验研究,得出了垂直压力、含水量及土工合成材料的粗糙度对筋土之间剪切性能的影响规律.

关 键 词:粗糙度  直剪试验  垂直压力  含水量

Abstract: The friction mobilized between the soil and reinforcement is an import ant design parameter of reinforced structure.In this paper the mechanism of int eraction between clay and three geosynthetics with different surface roughness i s studied through direct shear test under different normal stresses and water co nt ents. Based on the test result,stress-strain relationship is studied systemati cally. Some important conclusions and suggestions which can be used to make rese arch and design are presented.
Keywords:surface roughness  direct shear test  normal stre sses  water contents
