摘要
以桂林红黏土为研究对象,对不同黏粒含量的桂林红黏土进行失水开裂试验,并对裂隙发育特征进行了分析。结果表明,黏粒含量和初始含水率的变化对红黏土失水速率未产生明显的影响,温度对红黏土失水速率影响较大;红黏土的裂隙发育过程大致可以分为3个阶段,第1阶段为裂隙产生阶段,第2阶段为裂隙扩展阶段,第3阶段为裂隙稳定阶段。初始含水率和黏粒含量对土体裂隙的最终形态影响显著。
The Guilin red clay was taken as the research object.The water loss cracking tests on Guilin red clay with different clay content was conducted,and the characteristics of fracture development were analyzed.The results show that changes in clay content and initial moisture content have no significant effect on the water loss rate of red clay,and temperature has a greater impact on the water loss rate of red clay;the development of cracks in red clay can be roughly divided into three stages.The first stage is the fracture generation stage,the second stage is the fracture expansion stage,and the third stage is the fracture stabilization stage.The initial moisture content and clay content have significant effects on the final shape of the soil cracks.
