利用北调江水补充调蓄石家庄地下水的工程技术方法探讨

石家庄是中国北方水资源危机较严重的城市之一,已形成了超采地下水的巨大降落漏斗。结合其毗邻滹沱河宽阔河滩,地面水可直接入渗补给降落漏斗内地下水的有利水文地质条件,实施利用北调江水补充调蓄地下水工程,将具有现实意义。该文针对北调江水可能存在的不同水质情况,应用现有较适宜的地下水调蓄方法和相关的水质净化技术或研究成果,选择滹沱河河道、河漫滩上采砂坑及其他有利的条件场地等,就利用北调江水补充调蓄地下水工程,进行了相关技术方法探讨,提出一个较适宜的工程技术方案,以期能为石家庄水资源的战略调控服务。

Engineering technology of recharging groundwater in Shijiazhuang with water diverted from the Yangtze River

Shijiazhuang is one of the cities suffering severe shortages of water resources in northern China,where a huge cone of depression has formed because of excessive exploitation of groundwater.Shijiazhuang is on the broad beach of the Hutuo River and its hydrogeological conditions allow surface water to directly penetrate into the cone of depression and recharge the groundwater.So,it is practically significant to recharge groundwater in Shijiazhuang the water diverted from the Yangtze River.According to different qualities of water from the Yangtze River,by using the existing appropriate groundwater recharging methods and related water purifying technologies and selecting the Hutuo River watercourse,sand pits on flood land and other favorable sites,the technologies of recharging Shijiazhuang groundwater with water from the Yangtze River are discussed and an appropriate engineering technology scheme is put forward,which is expected to serve the strategic control and management of water resources in Shijiazhuang.
