城市雨水泵站对河道护岸影响的初步研究

Preliminary Study on the Impact on Urban Rainwater Pumping Station on River Banks

本研究针对雨水强排泵站流量过大引起的河道护岸冲刷问题,以上海市桃浦科技智慧城为例,建立水动力计算模型,通过计算得出降雨期间雨水强排泵站流量与临近河道最大流速的关系曲线,提出河道流速与泵站流量相关公式,分析泵站流量对河道护岸的影响,为类似地区的水务规划设计提供技术借鉴。

This study aimed at the structural instability of the river banks caused by excess flow of urban rainwater pumping station.Taking Taopu smart city in Shanghai as an example,this article built a hydraulic calculation model, found the relation curve between the flow of rainwater pumping station and the maximum flow velocity of the river nearby by computation. An empirical equation was provided for calculation of the maximum flow velocity. The author analysed the impact on the river banks, and provided technical support for the similar land in water planning and design.
