| 摘 要： | 水淹坝岩溶内涝是安顺市西秀区发育最大范围的岩溶内涝,严重制约了当地经济发展。本文以岩溶地下水系统为单元,通过开展1:10000水文地质调查、地球物理勘探、水文地质钻探等手段,查明内涝所在区的岩溶发育特征、水文地质条件。在此基础上分析得出,水力坡度小、岩层倾角缓造成地下河管道淤塞;人类工程活动使有水落水洞口堵塞,加之广阔的集雨面积和连续的强降雨是造成水淹坝岩溶内涝的主要原因。通过对水淹坝内涝成因分析,为岩溶内涝灾害综合整治提供参考依据。

| Abstract: | The Shuiyanba karst waterlogging is the most developed karst waterlogging in Xixiu District,Anshun City,which seriously restricts the development of local economy.This paper has a discussion on karstification,hydrogeological features and genesis of the karst waterlogging in the studied area based on 1:10000 hydrogeological survey,geophysical exploration and hydrogeological drilling data.The study indicates that gently dipping formation,low hydraulic gradient,siltation of underground river pipes,blockage of sinkholes caused by human engineering activities and vast catchment area and continuous heavy rainfall are responsible for the formation of the Shuiyanba karst waterlogging. |
