| Abstract: | On the basis of the extended Drucker-Prager yield criterion in ABAQUS program,Mohr-Coulomb equivalent area circle yield criterion is adopted and how the equivalent material parameters are calculated is described.The divergence is assumed as the flag to tell the slope sliding.And the stability of a certain typical soil slope is analyzed by use of Mohr-Coulomb yield criterion with different circle,such as circumscribed circle,inscribed circle,internal tangential circle and equivalent area circle.When the mate... |
