为了研究坡顶处堆载宽度、堆载范围与坡面的最小距离以及堆载大小对边坡稳定性的影响,采用大型岩土有限元软件GTS-NX并结合正交试验设计方法,对堆载边坡的稳定性进行敏感性分析.计算结果表明:边坡的稳定性系数会随着坡顶堆载作用宽度的加宽、堆载范围与坡面最小距离的减小以及堆载荷载的增大进而减小;以上三种因素通过极差分析,其敏感性由大到小为:均布堆载大小(q)>堆载作用宽度(B)>堆载作用范围距坡面的最小距离(d). |

In order to study the effect of the stacking width at the top of the slope,the minimum distance between the load range and the slope,and the effect of the size of the load on the slope stability,sensitivity analysis of stability of stacking slope was carried out by using large-scale finite element software GTS-NX combined with orthogonal test design method,the calculation results showed that the stability coefficient of the slope reduced with the width of the stack at the top of the slope widening,the minimum distance between the load range and the slope decreasing and loading load increasing,through the range analysis the three factors,Its sensitivity from large to small were uniform heap size(q)>The width of the load(B)>The minimum distance from the slope to the load(d). |
