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。
When using the upper bound limit analysis method for slope stability analysis, the sloping strip method is generally adopted to disperse the sliding soil. The method uses fewer straight lines to connect and then subdivides the straight line segments between two points by the cubic spline function To form the sliding bottom surface. The two commonly used internal slant mode are analyzed comparatively. The analysis of the examples with closed solutions proves the correctness of the program. The analysis of the other two typical slope shows that two kinds of internal slope There is a big difference between the flexibility of processing and the efficiency of analysis.
