| 摘 要： | 为了研究弃土场边坡挡墙加固中,挡墙基底在不同换填宽度条件下以及在同一宽度条件下不同换填深度对弃土场边坡稳定性的影响。基于有限元强度折减法理论,利用midas GTS有限元软件,依托工程实例建立二维有限元模型。分析了不同换填宽度及换填深度情况下弃土场边坡在暴雨工况下的稳定性系数。研究发现在同一换填宽度条件下,换填深度对边坡稳定性起决定性作用;只有在换填深度达到一定值时,增加换填宽度才对边坡稳定性有提升作用。

| Abstract: | In order to study the reinforcement of the slope retaining wall of the spoil ground,the influence of the retaining wall base on the stability of the spoil slope under different filling width conditions and different filling depths under the same width condition.Based on the finite element strength reduction method theory,the two-dimensional finite element model is established by using the midas GTS finite element software and relying on engineering examples.The stability coefficients of the spoil slope under heavy rain conditions under different replacement widths and replacement depths are analyzed.It is found that under the same replacement width,the replacement depth plays a decisive role in the stability of the slope;only when the replacement depth reaches a certain value,increasing the replacement width can improve the slope stability. |
