重庆红黏土三轴蠕变特性试验研究

Experimental study on tri-axial creep characteristics of red clay in Chongqing

为了研究重庆地区红黏土的蠕变特性,对原状红黏土进行了三轴压缩试验、三轴蠕变试验。根据三轴压缩试验,建立了红黏土的应力、应变关系,得出了红黏土抗剪强度参数与物理指标。

In order to investigate the creep characteristic of the Chongqing area red clay,theoriginal red clay were studied by tri- axial test and tri- axial creep test. The stress- strain relation for the original red clay was established. The relation between shearing intensity par- ameters and physical properties was obtained.According to the creep test for the red clay,the tri- axial creep curves and distortion characteristics under different confining pressure were obtained.
