| Abstract: | The safety factors and associated slip circular-arc are often influenced by some factors such as slices number, slope gradient, cohesion and friction angle of soil, pore water pressure etc. In this paper, the influences for the safety factors and associated slip circular-arc by the above factors are detailedly studied with optimization technique. Several available conclusions are drawn. |
