运动单元法与边坡稳定性分析

运动单元方法通过引进单元运动分析，静力分析和优化极值分析，自动完成岩土工程剪切破坏区和最危险滑动面的搜索，在此基础上求得不同工程问题的极限值。该方法具有严格的数学力学基础，适用于各类地质条件，岩性和几何形状复杂的岩土工程的极限分析。运动单元法是一种分析岩土工程地基极限承载，挡土墙极限土压以及边坡稳定性的塑性极限分析方法。

KINEMATICAL ELEMENT METHOD AND SLOPE STABILITY ANALYSIS

The kinem atics elem ent m ethod is introduced to evaluate com plicated problem s in geo-engineer- ing, such as analyzing slope stability, ultim ate bearing capacity of foundations and active or passive earth pressure. With this m ethod, the criticalsurface ofrock and soilengineering is searched gradually w ith opti- m ization approach, then ultim ate value can becalculated on the obtained criticalsurface. Based on the princi- ple ofkinem aticalelem entm ethod, the com plem ented forces acted atthe flexible boundaries and the calcula- tion ofthe factorofsafety ofslope are discussed firstly, then the stability ofa slope isanalyzed w ith the pro- gram ofkinem aticalelem ent analysis system .
