摘要
以粉质粘土、粗砂、石屑为填料,通过自制设备进行拉拔试验。研究土工格栅与其界面的摩擦特性,得到3种填料与格栅的界面似摩擦系数,对影响筋土界面摩擦特性的主要因素进行深入分析。
The pull - out test is carried out by using silty clay, grit and stone chip as filling materials via self-made equipment to investigate the frictional characteristics between the geogrid and its interface. As a result, the similar interface friction coefficients between three kinds of filling materials and the geogrid are obtained. Furthermore, the primary factors influencing the frictional characteristics of the reinforced soil interface are deeply analyzed.
