  • Experimental system of surrounding rock and lining structure under unequal surrounding pressure and water pressure
    Patent number: 11774335
    Abstract: The invention discloses an experimental system of surrounding rock and lining structure under unequal surrounding pressure and water pressure, comprising: reaction wall, lining structure, external water pressure loading mechanism, internal water pressure loading mechanism, prestress-loading mechanism, surrounding rock layer and monitoring device. The Experimental System can simulate the stress characteristics and related deformation characteristics of the surrounding rock of the tunnel and the lining structure of the water conveyance tunnel under complex internal and external loads in the actual environment, and can help to analyze and study the broken appearance of the lining structure and the crack distribution after cracking.
