Upper bound limit analysis of slope stability using rigid finite elements and nonlinear programming

  title={Upper bound limit analysis of slope stability using rigid finite elements and nonlinear programming},
  author={Jian Chen and Jian-hua Yin and Chiu Fan Lee},
In this paper, the development and application of a new upper bound limit method for twoand threedimensional (2D and 3D) slope stability problems is presented. Rigid finite elements are used to construct a kinematically admissible velocity field. Kinematically admissible velocity discontinuities are permitted to occur at all interelement boundaries. The proposed method formulates the slope stability problem as an optimization problem based on the upper bound theorem. The objective function for… CONTINUE READING
