引江济淮河南段输水河道周边地下水位变化规律研究
Study on the Variation Law of Groundwater Level Around the Water Conveyance Channel Caused by Henan Section of the Yangtze-to-Huaihe River Diversion Project
摘要
Abstract
The Henan section of the Yangtze-to-Huaihe River Diversion Project supplies water from the Xifei River in Anhui Province to Henan Province,of which,the Qingshui River conveyance length is 47.46 km,and the conveyance channel has leakage and groundwater re-charge problems.In this study,15 groundwater level measuring points were set up around the Qingshui River to monitor the variation law of groundwater level after the water diversion experiment of the project in early December 2022.The results show that the rise of groundwater level at the measuring points near the river is earlier than that at the measuring points far away from the river,and the rise of water level is higher than that at the measuring points far away from the river.The change rate of groundwater level at different measuring points is generally a normal distribution of rising first and then falling at the initial stage after water diversion.The maximum change rate of water level at the measuring points close to the river channel is significantly higher than that at the measuring points far from the river channel.Different stratum conditions have a great influence to the groundwater recharge,which is manifested as that when there is a permeable layer with a large perme-ability coefficient or a thick permeable layer in the stratum,there is a large risk of leakage.关键词
