摘要
岩溶地区的库区渗漏问题一直是水利工程中的热点和难点问题。河口村水库库坝区水文地质条件复杂,局部发育有较大规模的溶蚀现象,在总结岩溶发育空间分布规律的基础上,分析了影响岩溶发育的因素:本区的岩溶发育的分布与地质构造形迹的强弱、距离岸坡的远近、地表和地下水的强径流区以及风化卸荷作用密切相关,在此基础上分析了岩溶发育对水库渗漏量和水库防渗的影响,为水库渗漏问题的评价和防渗设计提供了依据。
Leakage problem is a hotspot and difficulty for hydraulic engineering in karst area.The hydrogeological condition of Hekoucun reservoir is complex,larger scale karst develops locally.Based on the analysis of the spatial distribution law of the karst development in this area,the influencing factors were studied.The karst distribution was closely related to the geological structure,distance to the river bank,movement of the surface water and groundwater,and the unloading and weathering of the rock.Thus the influence of the karst on the reservoir leakage was analyzed,which provided a reasonable basis for the leakage evaluation and anti-seepage design.
