围填海区域泵站群规模配置与渠网布置研究

针对围填海区域排涝需求，提出了综合考虑渠网特性、涝水过程及泵站空间位置的泵站群规模配置方法，并分析了渠网布局、泵站规模同区域特征的关系。临港工业区实例应用结果表明：（1）与对照方案相比，采取泵站群规模配置方法能有效降低泵站群总规模，同时减少水泵启闭次数。（2）渠网布局同区域特征存在明显的耦联关系。当形状系数超过临界形状系数时应采取三横四纵渠道布局方案，反之应采取两横四纵渠道布局方案。研究成果可为围填海区域排涝系统建设提供参考。

Scale allocation of pump stations and layout of channels over reclamation area

This paper describes a new method for scale allocation of pump stations over the reclamation area to meet the drainage demand, comprehensively considering the characteristics of the river network, flooding process, and the spatial locations of the stations. The relationship of the river network layout and pumping station scales versus the regional characteristics is examined. Application to the Lingang Industrial Zone shows that (1) Compared with the alternative schemes, adoption of this method can effectively reduce the total scale of the pump stations and the frequency of pump opening and closing. (2) There exists an obvious coupling between the river network layout and the regional characteristics: a layout of three horizontal channels and four vertical channels should be adopted in the case of the shape factor exceeding the threshold, and otherwise two horizontal and four vertical channels are optimal. The results would help construct drainage systems for reclamation areas.
