Calculation for Earth Pressure of Cavity Expansion Considering Displacement

Most of the studies on cavity expansion are about the analytical solutions of the stress distribution, and not related to the effect of soil properties on earth pressure. Aiming at the problem, the change law of passive earth pressure is analyzed by using the Mohr-Coulomb model, and the formula of earth pressure is summarized. The error value of calculation and simulation is small that the formulas can be directly used in practical engineering.
