黄土基坑边坡滑坡病害成因分析与防治对策——以准格尔煤矿选煤厂产品仓基坑边坡滑坡防治工程为例

Cause Analysis and Countermeasures against Slope Landslide of Loess Foundation Pit——Case Study of Landslide Control of Foundation Pit Used as Product Storehouse in Coal Preparation Plant of Zhunge'er Coal Mine

基坑边坡滑坡是建筑基坑失稳的一种特殊形式和诱发因素,由于其变形破坏形式与边坡滑(垮)塌相近,在具体工程实践中,容易造成判断失误,进而导致防护工程措施设置失当。本文通过具体工程案例,从工程地质角度对黄土基坑边坡滑坡的病害成因进行综合分析,进而对相应的工程防护措施提出建议。

Slope landslide of foundation pit is a special kind and the inducing factor of instability of architectural foundation pit. Because of its similarity to slope collapse in characteristics of deformation failure, it is hard to distinguish in particular engineering practice, causing unreasonable design of engineering project for stabilization. By means of case study, this paper takes a comprehensive cause analysis of slope landslide of loess foundation pit in the viewpoint of engineering geology, and then the appropriate countermeasures for protection and reinforcement of the foundation pit are proposed.
