| 摘 要： | 依托兰州南绕城典型路堑边坡工程,运用有限差分FLAC3D软件,以暴雨无支护和暴雨有支护两种工况对所选边坡稳定性进行模拟分析.结果表明:暴雨无支护结构工况下,边坡处于不稳定状态且有潜在滑动面;暴雨有支护结构工况下边坡处于稳定状态,与实际情况相符.同时,对格构锚固后的边坡位移、应变增量、塑性区分布、支护结构受力等情况进行了...

Evaluation of Lattice Support Effect of Cutting High Slope under Rainstorm Condition |
| |
| Abstract: | Based on the typical cutting slope engineering in the south ring expressway in Lanzhou, the stability of the selected slope was analyzed by the finite difference FLAC3D software under the two working conditions of rainstorm without support and rainstorm with support. The results show that the slope is in an unstable state and has potential sliding surface under the working condition of rainstorm without support structure, while the slope is in a stable state under the working condition of rainstorm with support structure, which is consistent with the actual situation. At the same time, the displacement, strain increment, distribution of plastic zone and stress of supporting structure of the slope are analyzed after lattice anchoring. The lattice full-length adhesive anchor bolt support improves the overall stability of the slope. |
