依据《上海虹桥综合交通枢纽规划控制要素》(V3.0版)、《上海虹桥综合交通枢纽地区水利规划》,本文对水系布局、河道断面布置提出深化论证思路,通过方案比选,合理确定工程规模。坚持排水面积与调蓄量不变的原则,河道采用复式断面,既保证了河道的防汛排水能力,又有效解决了平原地区城市河道防汛排水与节约用地之间的矛盾,值得借鉴。 Based on “Control Elements of Shanghai Hongqiao Integrated Transport Hub Planning” (V3.0) and “Water Conservancy Planning of Shanghai Hongqiao Integrated Transportation Hub Area”, this paper puts forward some suggestions on deepening the feasibility of water conservancy layout and river channel layout. Through project comparison and selection, scale. Adhere to the principle of constant drainage area and storage capacity, the use of duplex sections of the river course not only ensures the flood control and drainage capacity of the river, but also effectively solves the contradiction between urban flood control drainage and land-saving in the plain areas, which is worth learning from.
