Abstract: Different equivalent area Drucker-Prager yield criteria on π-plane,such as DP4,DP5 and DP6 yield criteria,can give an approximate estimation of soil failure strength under plane strain condition,which is why the equivalent area DP yield criteria are widely used for two-dimensional slope stability analyses.Combining true triaxial strength failure tests of sand,it demonstrates from quantitative point that the DP4 yield criterion is conservative for safety factor prediction of slope stability,where...

Key words: yield criterion； strength reduction finite element method； two-dimensional stability； three-dimensional stability； safety factor；
