Abstract:

Different equivalent area Drucker-Prager yield criteria on? plane, such as DP4(meaning projection areas of Drucker-Prager and Mohr-Coulomb yield criteria being equal on ? plane) , DP5(meaning projection areas of Drucker-Prager and Matsuoka-Nakai yield criteria being equal on? plane) and DP6(meaning projection areas of Drucker-Prager and Lade-Duncan yield criteria being equal on ? plane) yield criteria, can give a approximately estimation for soil failure strength under plane strain condition, this is why these equivalent area Drucker-Prager yield criteria are widely used in two-dimensional slope stability analyses. Combined true triaxial strength failure tests of sand, it is demonstrated from quantitative point that DP4 yield criterion is conservative for safety factor prediction of slope stability; whereas DP5 and DP6 yield criteria, which will exert soil shear strength more effectively under plane strain status, both give a better safety factor predictions for slope stability analyses, thus computation precision of slope safety factor is further improved by using DP5 and DP6 yield criteria in the end.

Key words: Drucker-Prager yield criterion, strength reduction finite element method, slope stability, safety factor
