基于ADINA的露天煤矿高边坡变形及稳定性分析

Deformation and Stability Analysis of Open-Pit Mining High and Steep Slope Based on ADINA

摘要: 为掌握露天煤矿高边坡变形规律及应力分布特征，基于现场工程地质调绘分析，运用ADINA分析了宝日希勒露天煤矿边坡的应力分布及变形破坏机理，并根据强度折减法理论对边坡稳定性进行计算分析，结果表明：边坡可能沿软弱夹层滑动破坏，且破坏模式为顺层–后缘穿层滑动(折线滑动)。

Abstract: In order to grasp the opencast coal mine high slope deformation law and stress distribution cha-racteristics, through the analysis of the engineering geological investigation, the paper analyzes the stress distribution and the deformation failure mechanism of the slope of Baorixile open pit coal mine based on ADINA. Slope stability is analyzed based on the strength reduction theory. The results show that the slope may be sliding failure along the weak interlayer and that the failure mode is bedding-trailing edge wear layer sliding (fold line sliding).
