摘要
分析了黏土的应力诱导各向异性发展(消失)的方式及变形特性,对具有不同应力历史的黏土进行了压密试验,在异向压密的时候,都有一些应变是以等方向形式发生的.相同应力状态的黏土,等方向压密以后,具有剪切历史的黏土比具有异向压密历史的黏土的各向异性发展相对小一些.
With different stress histories, the heteroscedasticity compression tests of clay with different stress histories are carried out using triaxial testing machine for finding out the formation of the heteroscedasticity developing (disappearing) and the deforming characteristics induced by stress. The formation of the heteroscedasticity developing and disappearing and its effect on deforming are analyzed.
