摘要
采用极限分析上限法进行土坡稳定分析时,一般采取斜条分法对滑动土体进行离散,采用较少点的直线连接,然后利用三次样条函数细分两点之间的直线段的方法来形成滑动底面,对两种常用的内部斜条分模式进行了比较分析,对具有闭合解算例的分析证明了程序的正确性;对其他两个典型土坡的分析表明,两种内部斜条分模式在处理的灵活性以及分析的效率上存在较大差别。
The inclined slice method is usually used in the upper bound limit stability analysis of soil slopes. The slip base can be generated by several nodal points and spline functions. Two procedures for the generation of interslices are used. The slope which has theoretical values is studied by the programs used in this paper and the result is in good agreement with theory. Two other soil slopes are analyzed and a comparative study is made of the performance of the two procedures.
