洪江水库右岸岩溶渗漏特点与防渗处理优化设计探讨

Features of Karst Leakage and Optimization Design for Imperviousness Management in Hongjiang Reservoir

为查明洪江水库的渗漏模式,通过运用水文地质勘察手段,在地表地质调查、物探和连通试验等工作成果分析的基础上,用以指导并布置钻孔勘探来查明水库的渗漏特点和防渗边界条件,为进一步优化帷幕灌浆设计提供地质依据。经对实施效果评价,防渗效果良好,说明优化设计方案合理,完全达到防渗设计目的,可为岩溶地区水库渗漏处理提供借鉴经验。

Basis on hydrogeological survey and geophysical prospecting,this paper gives an example of Hong Jiang reservoir to illustrate how to find the features of reservoir leakage and boundary conditions of seepage control by drilling exploration. And it can provide a basis in curtain grouting optimization design. Through implementation effect evaluation,we thus conclude that the optimization design has a good anti seepage effect,fully achieves purpose and can provide reference experience for reservoir leakage treatment in karst region.
