Changsha 410083, China）Abstract: Based on the stability analysis for slope with polygon elements, the equilibrium of elements was evaluated by adapting fictitious force acting at boundary of element to calculate factor of safety, the behavior of the fictitious force was studied while the factor of slope safety changes,the procedure was discussed to obtain the factor of slope safety in an iterative way if the adopt fictitious force was vanished finally.

The mathematical programming formulation and related solution procedure are established by the traditional BEM. Through the discretization of space and time, the elastoplastic stress simulation method and reduce-basis technique are adopted to construct the self-equilibrium stress field. The numbers of variables and constraint equations in the resulting mathematical programming formulation are reduced greatly and then the dimension obstacle of computation in 3-D limit and shakedown analysis is overcome.
