Accuracy of Two-Dimensional Limit Equilibrium Methods in Predicting Stability of Homogenous Road-Cut Slopes

Although limit equilibrium methods are widely used by engineers and scientists in predicting the stability of homogenous slopes, their use has been demonstrated to present significant errors due violation kinematic static admissibility. The concern is often voiced regarding accuracy (LEMs) solutions slopes. There no exact or charts available that could be check LEMs solutions. study rigorous upper lower bounds analysis based on finite element formulations bound theorems benchmark develop an classification chart slope. Six case studies road-cut slopes vary with material properties were effect increase strength depth was considered. results have shown Janbu simplified closely related those error ranging from 1 7% various slope materials. Meanwhile, Corp Engineer 2 found overestimate among other methods, 12 17% cases. Based developed.
