在对长江三峡库区黄腊石大石板滑坡的调查研究和分析的基础上,概括介绍了大石板滑坡的概况和其排水治理方案,对其地下水位监测进行了分析与研究。然后,模拟了8个滑坡地下排水治理方案,利用geo-slope软件进行分析与计算。研究结果表明:从排水效果和经济性两方面综合分析,得出了大石板滑坡地下排水井和纵向平硐位置布置在滑坡的中前缘为最优方案。
Based on the investigation and analysis of the Huangshi stone slab landslide in the Three Gorges Reservoir Area, the general situation of the Dashila landslide and its drainage management are summarized. The monitoring and monitoring of the groundwater level is analyzed and studied. Then, eight landslide underground drainage treatment programs were simulated and analyzed and calculated by using geo-slope software. The results show that the optimal scheme is that the location of underground drainage wells and vertical adit of Dashi slanting landslide is located in the middle front of landslide from the comprehensive analysis of drainage effect and economy.
