Abstract
A method of slope stability analysis, which can utilize numerical solutions of the finite element seepage analysis, was proposed in this paper through the way of expressing the equations in terms of effective slice weight and seepage forces. Some numerical calculations were done on simple earth slopes under a steady seepage state, to discuss the difference in features of stability evaluation between different ways of stability analysis, by comparing the results with those by the way of using total slice weight and pore-water pressure along sliding surface and with those by a practical method of slices published before. Incidentally, a calculation method of the values of hydraulic gradient and directions of flow lines from FE solutions of total head distributions and a way of introducing the effects of seepage forces acting on finite elements in the stability analysis were presented.
