| Abstract: | This article introduces basic hypothesis,calculation theory,program frame of accelerating simplex method in the aspect of finding the best danger surface and the least security coefficient,and expounds some limitations in this method.Moreover this article puts forward improvement scheme in allusion to these limitations.At last combining practical projects this article explains the application process of accelerating simplex method after improvement,by this accelerating simplex method the best danger surface of slope can be accurately found the least security coefficient can be formed automatically in the course of searching.The accelerating simplex method has some theoretic significance and practical engineering value by way of the new measure of finding the best danger surface. |
