摘　　要：山区矿山道路建设切坡往往诱发地质灾害,为了保障矿区安全生产运营,本文以某矿山进矿道路滑坡为例,对该滑坡的基本特征、影响因素及形成机制进行综合分析,利用反演法及室内试验综合确定了滑坡计算参数,采用平面滑动法对该滑坡的稳定性进行了计算及评价,通过计算可知:进矿道路现状边坡整体处于欠稳定状态,可能再次发生顺层滑动。山区矿山道路顺向坡切坡易造成边坡的失稳,对山区矿山道路切坡提出治理措施建议,具有一定的研究意义。Cutting slope of mine road construction in mountainous area often induces geological disasters.In order to ensure the safe production and operation of the mining area,this paper taking the landslide of a mine access road as an example,analyzes the basic characteristics,influencing factors,and formation mechanism.The parameters of landslide calculation are determined by inversion method and laboratory test,the stability of the landslide is calculated and evaluated by the plane sliding method.The results show that the slope of the mining road is in an understable state and may slip along bedding again.Slope instability is easily caused by the forward slope cutting of mine road in mountainous area.The research on slope cutting treatment of mine road in mountainous area has certain practical significance.

关 键 词：进矿道路 滑坡 平面滑动 稳定性
