Equal shear strength slope stability calculation method
The invention provides an equal-shear-strength slope stability calculation method which comprises the following steps: a region division step: dividing a composite foundation filling slope into a first region, a second region and a third region; a model conversion step: dividing each pile body in the first area into a plurality of repeated unit bodies with square cross sections, converting the circular cross sections of the pile bodies into rectangular cross sections with the same area, and converting the cylindrical pile bodies into rectangular piles; a re-modeling step: dividing the slope filling of the second area into areas with different weights, obtaining the equivalent weight of the second area for modeling, and re-establishing a second area model above the first area; and a step of calculating a slope stability coefficient: obtaining the height of the slope in the second area and the length of the pile body to determine a third area range, establishing a completed two-dimensional limit equilibrium method analysis model, and calculating the slope stability coefficient in the second area.
本发明提供了一种等抗剪强度边坡稳定性计算方法，包括：划分区域步骤，将复合地基填方边坡划分为第一区域、第二区域和第三区域；转化模型步骤，第一区域内根据每根桩体划分为若干重复的横截面为正方形的单元体，再将桩体的横截面由圆形转化为同等面积的矩形截面，桩体由圆柱形桩转化成矩形桩；重新建模步骤，将第二区域的边坡填土划分为不同重度的区域，获得用于建模的第二区域等效重度，重新建立第一区域上方的第二区域模型；计算边坡稳定性系数步骤，获取第二区域内边坡的高度、桩体长度以确定第三区域范围，建立完成的二维极限平衡法分析模型，计算得出第二区域内的边坡稳定性系数。
