Strain Finite Element Analysis of the Slope Stress Criterion Based on D-P Yield
Based on Drucker-Prager (D-P) yield criterion,we analyze the slope stability by use of the force and displacement convergence criteria as a failure criterion and the ANSYS analysis software.The results show that compared with the traditional method,finite element strength reduction method can more truly reflect the state of the slope and the reduction factor obtained is closer to the actual situation.The method have certain advantages in the slope stability analysis.
