【摘要】 针对矿山在地下开采转为露天开采过程中，原地采区域在露天采场台阶开挖过程中对露天采场公路建设及运营的影响，进行了数值模拟分析，并对通过各种岩体介质的露天采场公路路基在台阶开挖和汽车运营过程中的稳定性进行了分析评价，得出了在不同条件下，如空洞地区、台阶材料介质、材料界面、开挖台阶与公路距离等对路基稳定性影响的评价。更多还原

【Abstract】 This paper gives the FE Simulating analysis of the effect on road construction in the process of mine open-cut, analysis and evaluates stability of road foundation during many rock material steps excavation, concludes that the different conditions, for example, the rock caves, steps and the dis tance between the steps and road have influence of the road foundation stability.更多还原
