摘要
对影响筋-土摩擦特性参数测试的几个主要试验条件进行了分析研究,提出了测试的合理取值与改进方法.进行了5种筋材的拉拔试验,得出了加筋土筋材在砂土中的摩擦特性规律和临界摩阻强度,对今后的筋材拉拔试验及工程应用具有参考价值.
Based on analyzing some main test conditions that affect frictional resistance characteristic between geosynthetics and earth, the reason value and improved way of pullout test are put forward.Frictional resistance characteristic and critical frictional resistance strength of geosynthetics in sandy soil are gotten by pullout test for five geosynthetics material.It is value for pullout test and engineering application.
