Developing petterson method to assess slope stability in three dimentional space

Abstract

    Evaluation of slope stabilization is a geological engineering issue which is very popular in practice. It has been widely dealt with by using plane method, but the disadvantage is that it does not take into account some factors. The author has studied and developed the plane method of Petterson to evaluate the slope stability in three dimensional space. By converting the slope mass of ellipsoid to hemisphere, the intergrals of sliding volume and surface area can be executed precisely in terms of maths and mechanical. This result can contribute to a complete method to apply in practice.
