浅议引汉济渭配水工程调蓄研究的关键问题

Key Issues on water distribution system of the water transfer project from Hanjiang River to Weihe River

引汉济渭工程是解决陕西关中地区缺水问题的战略性骨干调水工程。引汉济渭的水源区与南水北调中线工程水源区部分重合,为优先保障南水北调中线工程的供水水源,留给引汉济渭的可调水过程极不均匀,供水和用水需求过程匹配性差。引汉济渭工程建成后,配水系统的调蓄能力成为工程供水效益能否充分发挥的关键。本文从调蓄节点选址及工程设计参数、配水管网的流量设计参数、调蓄方案及其运行管理机制和地下水参与调蓄的边界条件及运用原则四个方面探讨了引汉济渭配水工程调蓄研究的关键问题。

The water transfer project from the Hanjiang River to the Weihe River is a strategic system on water resources allocation in Shaanxi province. The water source area of the water transfer project from the Hanjiang River to the Weihe River overlap that of the South to North Water Transfer project. To ensure the water supply of the South to North Water Transfer project, the process of water available for the water transfer project from the Hanjiang River to the Weihe River was uneven. So there was poor matching be- tween water transfer processes and water demand processes. When the project went into operation, the stor- age capacity of the water distribution system became the key issue of enhancing water supply benefits. This paper has made a preliminary discussion about the issue of storage capacity of the project, especially in four aspects： the location and engineering parameters of the reservoirs, the design discharge of the water supply pipe network, regulation scheme and its operation rules, utilization of groundwater and water storage.
