| Abstract: | In the analyses of slope stability aimed at securing engineering projects, a key is to identify potential sliding surfaces. For this purpose, we wrote out the two-dimensional and three-dimensional simulation programs, whose principles are briefly introduced in this paper. In the two-dimensional simulation four calculation models are proposed, while in the three dimensional simulation space, load and seepage effect are taken into account. This paper gives two simulation examples. The simulation result is basically in line with the measured result, especially in the shear strength of soil. |
