复杂地块条件下排水泵站与调蓄池合建的优化设计

Optimal Design of the Combined Construction of Drainage Pump Station and Storage Tank under Complex Land Parcel Conditions

以上海市宝山区张华浜东排水泵站和调蓄池的设计为例,针对泵站在进水条件较差、泵站位置狭小且不规则、雨水出水口位置受岸线码头阻挡等复杂地块条件下的不利因素进行了优化设计。提出了计算流体力学(CFD)进水流态模拟的优化分析、泵房与调蓄池合建式叠加布置的优化措施,并通过数模分析对穿越已建码头的出水口水流扩散参数进行了最低环境扰动的优化选择。

Taking the design of Zhanghuabang East drainage pump station and storage tank in Baoshan District of Shanghai as an example,the design was optimized under complex land parcel conditions of poor inlet,narrow and irregular location,and the blocked stormwater outlet by waterfront wharf.The optimal analysis of inflow pattern simulation by computational fluid dynamics(CFD)and the optimal joint construction measures of pump house and the storage tank up and down were proposed.The optimal selection of the minimum environmental disturbance for the outlet flow diffusion parameters crossing the existing wharf was carried out by means of the numerical modeling analysis.
