  • Strength parameters of slope rock and soil can have spatial variability. Unified strength parameters for numerical modelling of slope stability can't reflect the effect of this nature in the calculation results. A new method of numerical simulation for slope stability is proposed in this paper. It takes into account the spatial variable distribution of the strength parameters in the slope. Using the topography and survey data, the spatial variation of the strength parameters can be reformed into a cloud contour map. With the help of Visual Basic programming and FISH language, the contour data of strength parameters are added to the numerical simulation model. Simulation results show that the method is workable and is more accurate in indicating the deforming location and situation, with has a guiding significance on landslide deformation monitoring and treatment.
