摘　　要：边坡工程地质模型是研究边坡破坏模式和稳定性计算的基础。说明了边坡工程地质模型的内容、露天矿层状边坡的基本工程地质模型、近水平岩层边坡的破坏模式。在工程地质工作的基础上,划分工程地质岩组,研究岩体结构和地下水影响,建立了某露天矿东南帮边坡的工程地质模型,分析了可能的破坏模式是圆弧滑动和圆弧-顺层滑动,对不同破坏模式下的安全系数进行计算,评价了16#煤开采前后边坡的稳定性。Engineering geological model is base of studying on slope failure pattern and slope stability analysis.This paper illustrated the content of engineering geological model,the basic engineering geological model of bedded rock mass slope,the slope failure of flat rock strata based on achievements of past generations.Based on engineering geological works,the engineering geological model of southeast slope of some surface mine were built after dividing the engineering geological petrofabric and studying on the rock mass structure type and effect of groundwater,the possible failure pattern were analyzed and safety factor were calculated,which were circular sliding and circular-bedding sliding,the slope stability at present and after full extraction of 16# coal seam were evaluated.
