为了分析抗滑桩加固边坡的稳定性,将整体分析法应用于抗滑桩加固边坡的稳定性计算中,重新推导了加固边坡安全系数的计算公式。该方法以整个滑坡体代替传统的条块为分析对象,通过建立三力矩平衡方程而非传统的水平力平衡、竖直力平衡以及对一点的力矩平衡,实现了滑体的整体极限平衡稳定性分析。所得到的方程是刻度良好的,存在唯一的、安全系数为正的实数解,收敛范围大且迅速,具有良好的数值特性,并且适用于各种形式的滑动破裂面,可以方便地从二维向三维进行推广。最后通过算例验证了所提方法的有效性。
In order to analyze the stability of slope reinforced by anti-slide piles, the global analysis method is applied to the stability calculation of anti-slide piles reinforced slope, and the formula for calculating the safety factor of reinforced slope is deduced again. The method takes the whole landslide body instead of the traditional block as the analysis object, and achieves the overall limit equilibrium stability of the sliding body by establishing a three-moment balance equation instead of the traditional horizontal balance, vertical balance and moment balance. analysis. The obtained equation is well calibrated, and there is a unique real number solution with positive safety factor. The convergence range is large and fast, and has good numerical characteristics. It is suitable for various forms of sliding fracture surface and can be easily obtained from two-dimensional To three-dimensional promotion. Finally, an example is given to verify the effectiveness of the proposed method.
