摘要

[目的] 建立黄土地区铁路沿线边坡稳定性综合评判模型

评价山西省中南部通道DK29+860处黄土边坡的稳定性。[方法] 在综合分析黄土地区铁路沿线边坡各种影响因素的基础上

选取7个评价因子

按照稳定、次稳定、不稳定和极不稳定的边坡稳定性的分类标准

并利用信息扩散原理

与FLACR数值模拟软件计算结果进行对比。[结果] 运用模糊评判法评判该边坡处于次稳定状态

使用FLACR数值模拟软件模拟求解得该边坡稳定系数为1.18

两者评价结果基本一致。[结论] 该评价方法真实可靠

能够准确地评价边坡的稳定性。

Abstract

[Objective] To establish the comprehensive evaluation model for the slope stability ultimately in loess region along the railways and to evaluate the loess slope stability of the channel DK29 + 860 in Mid-southern Shanxi Province. [Methods] Based on the comprehensive analysis of various influence factors about loess slope along the railway

seven assessment factors were selected. According to the classification criteria of slope stability(stable

less stable

unstable and extremely unstable)

the principle of information diffusion was adopted to compare the seven factors with the results calculated by of the FLACR numerical simulation. [Results] The slope was in a steady state evaluated with fuzzy judgment method

the slope stability coefficient was 1.18 with the FLACR numerical simulation software. The two conclusions were basically identical. [Conclusion] Fuzzy evaluation method was reliable

it can evaluate the slope stability accurately in loess region along railways.
