STABILITY ANALYSIS OF EMBANKMENTS AND SLOPES

A simple but accurate method of stability analysis of embankments and slopes is developed to determine the critical earthquake acceleration that is required to bring a mass of soil, bounded by a slip line of any shape and the free surface, to a state of limiting equilibrium. At the same time, the usual factor of safety can be determined. It is based on the principle of limiting equilibrium and the method of slices. Effective stress strength parameters are used. A distribution of internal body forces is found based on a simple assumption. This depends on the geometry of the dam and the sliding surface as well as on the strength of the material. Though a computer is used for the calculations presented in the paper, it is not essential. As in any solution, the physical acceptability of the complete solution must be checked before accepting the result. It is suggested to use the critical acceleration as a measure of the factors of safety. /AUTHOR/
