红砂岩填料与土工合成材料的筋土界面特性实验研究

The Experimental Study on the Interface Characteristic Between Red Sandstone and Geosynthetics

红砂岩越来越多的被用作加筋土工程的填料,其筋土界面特性直接影响到工程的稳定性。通过拉拨试验,研究了红砂岩与六角形双铰合钢丝网、土工格栅的相互作用时的筋土界面特性,分析了红砂岩作加筋土填料时不同土工合成材料的摩擦特性规律,确定相应的界面参数,为红砂岩加筋土工程设计提供了设计指导。

Red sandstone is more and more used as filling material in reinforced earth engineering and its interaction characteristic with geosynthetics would affect the stability of project. The interaction characteristics of red sandstone and double twisted steel wire mesh, geogird were studied by pullout test in this paper; the friction characteristics between red sandstone and different geosyntheticses were analyzed and corresponding parameters were gotten. This work provided design guide for red sandstone reinforced earth engineering design.
