Abstract
The characteristic of vacuum-surcharge preloading reinforced soft foundation is introduced in this paper. Indoor simulation test is carried out according to different load rates to analyze stress path, strength,settlement and water discharge of reinforced soft foundation. The result shows that higher rate of vacuum load causes more water discharge, more soil shrinkage and higher stability of soil mass. The higher rate of surcharge causes larger settlement, and stress path is easier to close to failure line and thus unstable factors increase.关键词
