Quantitative Study on Criteria for Fem Evaluation of Slope Stability with Multivariate Linear Regressive Analysis
A quantitative study emphatically on the criterion for evaluating stability of homogeneous soil slope is discussed in this paper. At first, considering the three main parameters(cohesion force c、angle of internal friction φ、slope ratio λ)of the slope stability, parameters of the slope which is in limiting state of equilibrium are selected by traditional slice method. Secondly, the connectivity rate of equivalent plastic strain median in shear band of the slope is got by adopting the above parameters. At last, the criteria formula(y=
