Contact Mechanism Analysis between Soil Structure and Underground Structures under Seismic Forces
the soil-structure appeared slipped of roadway under earthquake, using the Coulomb contact surface model and built soil-structure of roadway contact model for analyzing, and got slip rule at different direction and position under horizontal and vertical direction and pointed out the corner as the weakness position; the beneath of roadway has more slipping; the vault is vulnerable to the level of shear failure; and gave reference for roadway structure for the seismic design.
