摘要
本设计以中卫一贵阳联络线BE106滑坡勘察报告为依据，分析了滑坡的工程地质 条件及基本特征。在此基础上研究了影响滑坡失稳的因素，进而分析了滑坡的成因机 制。然后对滑坡的稳定性进行了定性评价，并采用极限平衡原理和传递系数法，计算 出滑坡的稳定性系数和滑坡推力，对滑坡稳定性进行了定量评价。按照“经济合理， 工期短，工程技术可行，治理效果安全可靠”的设计原则，从中选取了抗滑桩+排水 工程的治理方案，对滑坡做了治理设计。
关键词:滑坡,稳定性，治理设计,抗滑桩，排水工程
Abstract
Based on the geo-technical data of the BE106 landslide, the geological condition about the landslide was studied, then the factors which tampered with the slope's stability were construed, the reasons which caused the landslide were analyzed and the landslide's stability was estimated. According to the unbalance thrust transmission coefficient method's principle and supposition, the landslide's stability coefficient was calculated. Then the landslide's stability was appraised. Based on the analysis, the treatment measure were advanced. According to the result of the slope stability calculation, the design principle was that the project cost was reasonable, time limit for the project was much less, the technique was possible and the project was simple and easy to construct. Finally, a revised designing program has been chosen, which included anti-slide pile and drainage works . At last, the slope's designation of remedying engineering was made.
Keywords: landslide, stability, anti-slide pile, drainage works
