摘要
南水北调水源进京后,部分水源拟调入密怀顺水源区回补严重亏损的地下水。为了使南水北调水源稳定持续地回补地下水,需要查明水源区干涸河道的入渗能力。研究利用双环渗透试验和河道自然入渗试验2种现场试验方法,确定了水源区潮白河、大沙河和雁栖河河道的入渗能力。研究表明:利用干涸的河道能够消纳规划的10 m3/s的南水北调水源水量。
After entering Beijing, part of water of South-to-North water transfer project will be transferred to Mi-Huai-Shun water sources areas to recharge groundwater which has been deficit. To make sure that South-to-North water recharge groundwater steadily and continuously, it is need to detect the recharge capacity of dry river channels. The double ring infiltration test and natural infiltration test were used to determine the capacity of recharging groundwater of Chaobai river channel, Dasha river channel and Yanqi river channel. The result shows that the recharge capacity of the dry river channels are 10 m^3/s higher than planned capacity.
