The research of the damage in shear zone of viscous soil

Compacted cohesive soil is contacted with the pressure of static water and strain rate,under low confining pressure showing soften,in high confining pressures showing harden. In the same water content,cohesive soil under different confining pressure along with the increase of confining pressure,the same axial strain corresponding to partial stress increases,degree of compaction for some time,moisture content is higher,the greater the cohesion,friction angle is smaller,the shear strength of cohesive soil is weaker; fixed water content,compaction degree taller,cohesion and friction angle is bigger,smaller,shear strength is greater. Use of type TSZ10-1. 0 strain control type three axis instrument,Sichuan Province of cohesive soil in Mianyang area were conventional triaxial compression tests,were studied in different confining pressure and water content of cohesive soil under the relationship of stress and strain,shear strength index,and the viscous soil shear zone is used to simulate the failure analysis.
