【摘要】 在DJS剪力仪上,利用常州产有纺土工织物分别对砂土(干砂)和黏土(2种不同含水量的黏土)进行了剪切试验,确定土—土工织物接触面的合理参数与性质.结果表明,界面抗剪强度与界面法向应力成线性关系,其大小与土的种类及含水量有关;界面剪应力τ与剪位移ΔL为非线性关系,可用双曲线来拟合.更多还原

【Abstract】 The soil-fabric and spins produced by Changzhou were used for friction test to sandy soil(dry sand) and the clay(two kinds of different water content clay),respectively,on the shearing force meter of DJS.The parameters and nature of the soil-fabric interface were determined.The results showed that the interface shearing stresses τ and displacement ΔL can be fitted to a hyperbolic curve.更多还原
