竹筋加筋土筋土界面摩擦特性试验研究

Testing study on interface friction characteristics of bamboo reinforcements and earth

针对临时工程使用后复耕问题,将竹筋作为筋材应用于加筋土结构,并通过筋土界面摩擦试验对竹筋加筋土界面特性进行了研究,结果表明:在相同条件下,加筋土界面特性远远优于素土,竹筋加筋土的界面强度稍高于土工格栅加筋土;竹筋的间距对加筋土界面强度的影响较大;作用于竹筋加筋土的压力大小直接影响加筋土的加筋效果。

To the problem of rehabilitation after the temporary engineering, bamboo as the reinforced material, is used to the reinforced earth structure. And the interface characteristics between bamboo reinforcements and soid are studied with direct shear fraction test. The results show that ： in the same conditions, the interface characteristics of reinforced earth is much better than soid. And more, the interfacial friction strength of bamboo reinforced earth is bigger than that of geogrid reinforced earth. Spacing between the bamboo has the great influenceon on the interfacial friction strength of bamboo reinforced earth. The pressure acting on the bamboo reinforced earth directly impacts the strength of reinforced earth.
