张家港市五干河排涝泵站建设规模论证研究

Study and Demonstration on Construction Scale of Wugan River Waterlogging Drainage Pumping Station in Zhangjiagang City

摘要:

近年来，极端天气频发，张家港市遭受洪涝灾害，损失严重。为降低发生洪涝灾害的风险，张家港市正在加快各片区的防洪排涝设施建设。基于张家港市五干河排涝泵站的改扩建工程，采用Mike 11构建了片区的水文水动力模型，并结合无锡、陈墅等6座水文测站的实测数据进行模型率定及验证，其后对五干河排涝泵站在不同建设规模下开展相关的水文水动力计算。根据计算结果，建议该排涝泵站的建设规模由五干河节制闸净宽12 m扩建为净宽28 m，新增一座30 m³/s的排水泵站。

Abstract:

In recent years, the extreme weather occurs frequently, and Zhangjiagang City has suffered serious losses from flood and waterlogging disasters. In order to reduce the risk of flood and waterlogging disasters, the construction of flood control and waterlogging drainage facilities is speeding up in various districts of Zhangjiagang. Based on the reconstruction and expansion project of the Wugan River Waterlogging Drainage Pumping Station in Zhangjiagang City, Mike 11 is adopted to build the hydrological and hydrodynamic model for the districts, and the model calibration and verification are conducted in combination with the measured data from six hydrological stations in Wuxi and Chenxi. And then the related hydrological and hydrodynamic calculations are conducted for the Wugan River Waterlogging Drainage Pumping Station under the different construction scales. According to the calculation results, it is recommended that the construction scale of this pumping station is expanded from a clear width of 12 m for the Wugan River Check Sluice to 28 m, and a new 30 m³/s drainage pumping station is built.
