摘要

在大型土与结构接触面循环加载剪切仪上添加了拉拔试验模块，进行了大尺寸的粗粒土与土工布接触面的单调和往返剪切试验以及土工布拉拔试验。剪切试验结果表明，粗粒土与土工布接触面出现了一定程度的应变软化，相对法向位移的变化受法向应力影响很大，并表现出异向性。土工布拉拔试验结果表明，由于土与土工织物接触面的剪胀造成该类接触面的抗剪强度与法向应力不再是线性关系；将接触面剪切试验和拉拔试验方法结合起来是研究土与土工织物接触面力学特性较为全面和合理的手段。

Abstract

A series of tests were performed to investigate the monotonic and cyclic behavior of the interface between geotextile and soil. A functional module for geotextile drawing test was appended to a large scale cyclic test apparatus for soil-structure interface. The monotonic and cyclic shear tests of the interface between geotextile and gravel as well as geotextile drawing tests were conducted with the apparatus. The interface was found to exhibit strain-softening and obvious aeolotropic normal displacement which was affected by the normal stress. The drawing test results show that the shear strength of the interface is not proportional to the normal stress because of its dilatancy behavior due to shear application. The combination of the shear test and geotextile drawing test is recommended as a rational test approach for a comprehensive understanding of the behavior of soil-geotextile interface.
