In the past few years,limit analysis theory has been widely applied in slope stability analysis.First,the nonlinear strength parameters cohesion ctand internal friction angle φtwas introduced through the tangent method on the basis of upper bound theorem and quadratic parabola failure criterion.Secondly,considering the characteristics of small tensile strength of loess and prone to tension crack,a limit height formula and stability coefficient formula of loess slope was deduced in the failure mode of fissure-linear and logarithmic spiral.Finally,the Luochuan uniform loess slope stability was calculated with plastic limit analysis method thought SQP(sequential quadratic programming algorithm) and it was compared with the limit equilibrium method.The results show the correctness of the method and the superiority in the field of nonlinear values.
