| Abstract: | By using high-pressure direct shear apparatus and triaxial electro-hydraulic servocontrolled testing system, as well as soil-concrete samples contained an interface modeling the contact surface between soil and shaft wall, the mechanical parameters of interaction between clay or sand soil and shaft wall sunk by the freeze method at great depth have been measured.Moreover, taking a shaft as an example, the application of those measured parameters to the analysis of shaft wall rupture has been introduced. |
