摘要
为科学开展沿海地区多约束条件下排水口门工程规模论证,以浦东新区北横河及其配套泵闸工程为例,基于平原地区数字河网水动力模型,以水闸最大过闸流量作为关键分析指标,评估排水效益变化趋势。基于固定河道断面和排涝泵站规模,分析24 h总排水量、代表断面流速等,综合考量社会经济发展需求,结合选址用地条件、对河势和外侧航道的影响以及泵闸工程设计,对不同规模的设计方案进行比选。结果表明:外延伸段河道河口宽150 m、闸净宽72 m、泵站流量80 m3/s为最优河闸泵规模方案。该方案兼顾沿海地理特性、自然环境条件和社会经济需求,可为今后类似工程设计提供参考。
In order to scientifically carry out the drainage gates project scale demonstration under the condition of multiple constraints in coastal areas,taking Beiheng River and its supporting pumping station project in Pudong New Area as an example,the river network hydrodynamic model in plain area were adopted.By using the maximum discharge of the sluice as key index,the changing trend of the drainage benefits was analyzed.Based on the fixed river section and the scale of the drainage pumping station,the 24-hour total drainage volume and the flow velocity of the representative section were analyzed,and the social and economic development needs were comprehensively considered.The design schemes of different scales were compared and selected in combination with the site conditions,the impact on the river regime and the outer waterway,and the design of the pump gate project.The results showed that the width of the estuary of the outer extension section of 150 m,the net width of the sluice of 72 m and the flow rate of the pumping station of 80 m 3/s were recommended.The program takes into account the geographical characteristics,natural environmental conditions and socio-economic needs of the coast,which can provide a reference for similar work in the future.
