筋-土界面的作用特性直接决定加筋土工程的稳定性,所以筋材与填料的界面技术指标是土工加筋关键的设计指标。该文利用TZY-1型土工合成材料综合测定仪,以塑料土工格栅为加筋材料,以红粘土为填料进行直剪摩擦和拉拔摩擦试验,对不同压实度、不同加筋材料、不同速率下加筋土的摩擦特性、抗拔位移的变化规律进行了研究,为今后的加筋土工程应用提供参考,为相关工程的稳定性和变形分析提供依据。
The interaction characteristics of the tendon-soil interface directly determine the stability of the reinforced earthwork. Therefore, the technical index of the interface between the tendon and the filler is the key design index of the geotextile reinforcement. In this paper, we use TZY-1 geosynthetics tester, plastic geogrid as reinforcement material, red clay as filler for direct shear friction and pull-out friction test. The effects of different compaction degree, different reinforced materials, The friction characteristics and the variation rules of anti-pull displacement of reinforced earth under different rates are studied, which can provide references for the future application of reinforced earth engineering and provide the basis for the stability and deformation analysis of related projects.
