岩滩水电站水库岩溶浸没性内涝的研究

Study on water log caused by karst immersion surrounding Yantan Hydropower Station

岩滩水电站水库蓄水后，库边一些地段发生了较严重的内涝问题，淹没了部分农田，造成了一定的经济损失。给当地农民生活带来了困难。通过对该水库右侧东兰县拉巴片内涝的研究，分析了内涝的形成过程及勘察研究概况，认为当地受连续暴雨、岩溶管道排泄能力的制约，以及库水循地下河产生岩溶浸没，是产生内涝的主要原因。据此，提出了整治内涝的若干措施。

After the impounding of Yantan Hydropower Station,serious,water log occurred in some districts surrounding the reservoir.Some farmlands were inundated which caused certain economic loss and brought difficulties to the local people.Based on the survey and the analysis of water log evolution process in the Laba area of Donglan County,right to the reservoir,it is considered that the water log is caused mainly by the continuous rainstorm,restriction of water releasing capacity of karst pipes,and karst immersion due to buried river recharged by the reservoir water.According to this analysis result,several measures for treating the water log have been put forward.
