二滩水力发电厂滑坡整治设计

本文以探讨昔格达土体边坡的稳定及二滩电厂滑坡体的治理为目的 ,通过对滑坡体周围工程地质条件的勘察 ,分析形成滑坡的内因和外因 ,并以已经产生变形拉裂的边坡作为实例 ,说明二滩电厂滑坡的形成过程。最后根据滑坡的特征 ,通过宏观分析及定量计算 ,采取了挖孔抗滑桩、反压坡角、降低地下水位等综合治理措施 ,取得了良好的效果 。

The purpose of this paper is to discuss the stability of and the treatment to the landslide, which is developed in Xigeda\|Soil Slope in Ertan Powerplant Living area. With engineering geologic reconnaissance around the landslide, endogenetic and exogenetic ana\| lysis, and considering the existed deformation cracks inside the landslide, the establishment of this landslide has been described in detail. Based on the characters of the landslide, through macroanalysis and quantitative analysis, comprehensive measures have been adopted for the landslide treatment, including anti-slide pile, slope toe kentledge, and lowering the underground water table. Results are satisfied. The experience is ecpected for the futural reference in similar projects.
