平朔露天矿某黄土高边坡滑坡成因机理分析

Analysis of Formation Mechanism of a High Loess Slope at an Open-pit Mine in Pingshuo

从工程地质条件、水文地质条件及人类工程活动等方面入手,对山西平朔煤炭工业公司某露天矿黄土高边坡发生滑坡的成因机理进行分析。该滑坡表现出明显的牵引式破坏特征,其变形破坏过程可分为卸荷变形、蠕滑—拉裂、剧滑及趋稳等四个阶段。基于滑坡的成因机理,提出了相应的防治对策。

Starting from engineering geologic conditions,hydrogeologic conditions,the human engineering activity and etc.,the paper analyzes the formation mechanism of the high loess slope at an open-pit mine of Shanxi Pingshuo Coal Industry Corporation.The deformation of the landslide presents remarkable failure character of trail,the deformation and failure process can be divided into the unloading deformation,creep-crack,sliding quickly and stabilizing gradually.According to the formation mechanism of the landslide,some preventive countermeasures have been put forward.
