西北地区某黄土滑坡稳定性分析及治理措施研究

Stability analysis and preventive treatment measures to a landslide along expressway in Northwest Territories

以西北地区某高速公路滑坡治理为例,采用工程地质调绘、钻探及室内试验等手段,确定滑坡基本特征及相关特性指标。从滑坡区地形地貌、地质条件及降雨等方面分析其滑坡成因,并对其不同工况下的稳定性进行了分析评价。提出“抗滑桩+裂缝处置+完善防排水”的综合治理措施。其结果可为该地区滑坡治理提供科学依据和有价值的参考。

Taking the landslide treatment of a certain highway in the Northwest Territories as an example,this study uses engineering geological mapping,drilling,and indoor experiments to determine the basic characteristics and related characteristic indicators.The causes of the landslide were analyzed from the aspects of topography,geological conditions,and rainfall in the landslide area,and the stability under different working conditions was analyzed and evaluated.Propose a comprehensive governance measure of“anti slip pile+crack treatment+improved waterproofing and drainage”.The result for landslide control in the local area provides scientific basis and valuable reference.
