【摘要】：为了解决冲积平原区枯水季节水资源的不足,需要在对研究区开展综合水文地质勘查的基础上,针对地下截潜自流引水工程方案的可行性进行系列问题的论证。本文以广阔渠截潜自流引水工程为例,在查明和分析研究区地质环境条件的基础上,对研究区枯水期地下水资源量进行了评价,即分别采用不同方法对研究区枯水期地下水资源的储存量、补给量和可供自流开发利用的地下水径流量进行了计算,并对截潜自流引水工程运行过程中可能产生的环境地质问题进行了预测评估。结果表明:研究区枯水期地下水储存资源较丰富,但补给量和可供自流开发利用的地下水径流量较小,分别为0.527m3/s和0.449m3/s,远不能满足规划用水1.0~1.5m3/s的要求,说明在本区采用截潜自流引水方案是不适宜的,并建议采用直接导引储存汝河汛期水的方案。
[Abstract]:In order to solve the shortage of water resources in dry season in alluvial plain area, it is necessary to carry out comprehensive hydrogeological exploration on the basis of comprehensive hydrogeological exploration in the study area, and to demonstrate the feasibility of the project of underground submersible self-flow diversion project. In this paper, the groundwater resources in the study area during the dry season are evaluated on the basis of finding out and analyzing the geological environmental conditions of the study area, taking the project of intercepting submersible self-flow and diverting water from a wide channel as an example. That is to say, different methods are used to calculate the storage, recharge and groundwater runoff of groundwater resources during the dry season in the study area. The environmental geological problems that may arise during the operation of the diversion project of the intercepting submersible self-flow are forecasted and evaluated. The results show that the groundwater storage resources are abundant in the dry season, but the recharge and the groundwater runoff which can be developed and utilized by the self-flow are smaller, which are 0.527m3/s and 0.449 m3 / s, respectively, which can not meet the requirements of the planning water 1.0~1.5m3/s. It is shown that it is not appropriate to adopt the scheme of intercepting the submersible self-flow and diverting water in this area, and it is suggested that the scheme of direct guiding and storing the Ruhe water in flood season should be adopted.
