Abstract
In order to study the slope security situation during excavation and the relationship between the safety factor obtained from the finite element strength reduction and limit equilibrium method,using the finite element software ANSYS and limit equilibrium software SLOPE/W to calculate and analyze slope stability for excavation process various stages.By studying the intrinsic link of yield criteria the two methods adopted,finding the conversion methods of safety factor.Then using two safety factor to comparative analysis the two methods.The results are that during excavation process,the safety factor will appear first increases and then decrease phenomenon; in plane strain conditions,the slope safety factor calculated by using the plane strain Mohr-Coulomb criterion and conventional limit equilibrium method is the closest,the error is less than 8%.关键词
