摘　　要：对路堑高边坡进行快速评估,有利于更快地了解边坡危险情况,加快项目进程。采用加权TOPSIS综合评价法,选取6处不同类型的路堑高边坡进行稳定性快速评估,最后借助有限元软件通过数值建模进行验证,分析结果表明:软件仿真得出的边坡安全系数分布趋势与快速评估的结果整体相接近,关联性为0.817,表明基于加权TOPSIS的边坡稳定性评估能够起到预先评估的效果,可以作为对边坡稳定性进行预先评价的辅助手段之一。The fast evaluation for cutting high slopes facilitates understanding slope hazards and project processes. This paper adopted the weighted TOPSIS comprehensive evaluation method to evaluate the stability of six different types of cutting high slopes, and the result was verified by the numerical models established using the finite element software. The analysis showed that the distribution of the slope safety from the software's simulation was consistent with the result from the fast evaluation with a correlation of 0.817, indicating that the weighted TOPSIS-based slope stability evaluation could be effective in pre-evaluation and can be used as one of the auxiliary means for the pre-evaluation of slope stability.
