Abstract

The failure mechanism is the key problem for calculating the inclined failure loads adjacent to the undrained soil slope. Based on the undrained slip line field and boundary value problems, a new failure mechanism is proposed to evaluate the inclined failure loads adjacent the undrained slope. The rationality of the proposed method is proved by the definition of the ultimate load and the finite element upper bound analysis (FE-UB). It is not reasonable to assume the failure models since the failure models vary with the inclination load and angle. The proposed method gives a new evaluating indicator, which first calculates the inclined failure load and then determines the failure models.
