沈阳市地下水库建设的技术可行性分析

地下水在我国尤其是北方地区城乡供水中占较大比例。地下水库因具有地表水与地下水资源联合调控、多年调蓄、水资源战略储备及应急供水等功能而受到越来越广泛的关注。在分析地下水库基本结构的基础上,提出了建设地下水库的基本条件,并以沈阳市为例进行分析,给出了论证地下水库补给水源、补给区、地下水库储水空间估算及开采条件的具体分析与计算方法。最后利用建立的地下水流数值模型,模拟预测了地下水库建成后分别按常规水源与应急水源两种方式所产生的供水规模。结果表明,在研究区建设地下水库具有较高可行性。

Feasibility analysis of building groundwater reservoir in Shenyang city

Groundwater plays an important role in water supply in China, especially in North China. Groundwater reservoir is a new type of exploiting and utilizing groundwater resources, which has many advantages in integrated regulation of surface water and groundwater, multi-year regulation, water resource strategic reservation and emergent water supply, etc. Based on analysis of the essential structure of groundwater reservoir, the authors put forward the basic conditions of building groundwater reservoirs, taking the city of Shenyang as an example. The methods of analyzing recharge source and selecting recharge areas for groundwater reservoirs, estimating the storage capacity and exploiting conditions are demonstrated. A numerical model of groundwater flow in the study area is developed. Two water supply schemes of groundwater reservoir are worked out by simulation and prediction under the conditions of conventional water sources and emergency water sources. The results obtained show that it is feasible to build groundwater reservoir in the study area.
