靖西县庞凌水库工程设计

Design of Pangling Reservoir Project in Jingxi County

靖西县庞凌水库水源为地下河,库区位于岩溶区,渗漏情况复杂,库区内落水洞和溶洞发育。通过分析比较,选择了水库的坝址和坝型,论述了工程总体布置及主要建筑物的型式。通过封堵地下河、地下溶洞和断层破碎带等解决水库渗漏问题,从而改善该地区水源缺乏的现状,并解决靖西县长远的饮水问题。

Underground river is the water source of Pangling Reservoir in Jingxi County. The reservoir area is located in karst zone characterized by complex seepage, developed sinkhole and solution cavern. Dam site and dam type were selected based on analysis and comparison. The general layout of project and type of key structures were discussed. The underground river, karst cavern and fracture belts will be closed to stop seepage and solve the water shortage and long-term drinking water supply problem of Jingxi County.
