摘要
针对土工合成材料的筋—土界面特性,分析了界面摩擦加筋机理,进而提出了加筋效果的计算方法,并通过室内直接剪切试验研究了吹填砂和多种合成材料的筋—土界面的应力—应变关系及剪切强度参数,获得了不同条件对筋—土界面特性的影响程度。
Based on the interface characteristics of geosynthetics-soil,reinforcement mechanism of interface friction is analyzed.And then the evaluation method of reinforcement effect is put forward.Finally,the stress-strain relationship and shear strength parameters of reinforcing material-soil interface and hydraulic fill sand are obtained with indoor direct shear test.Thus,the impact of different conditions on the characteristics of reinforcement-soil interface is gained.
