Experimental studies of mechanical parameters of soft soil under different stress paths in the Tianjin Binhai New Area

By studying the marine soft clay 9-18 m below the land surface,on which many underground projects are laid in the Tianjn Binhai New Area,the consolidated-undrained triaxial compression test(CU),unconsolidated-undrained triaxial compression test(UU) and simulated pressure path tests(DEP) of excavation are carried out on the stress and strain controlled triaxial shear penetration apparatus.According to the experimental results,behaviors of soft soil under different stress paths are related to init...
