香港地铁黄竹坑站施工阶段雨水系统影响模拟评估

Evaluation of the effects of storm water system on the construction of the Wong Chuk Hang subway station in Hongkong subway

香港地铁南港岛线(东段)黄竹坑站将建于黄竹坑排洪渠的上方。施工拟在旱季进行,施工过程中有减小排洪渠过流断面的风险。通过选用InfoWorksCS和MIKE11两种模拟软件,建立水力模型,模拟施工过程对上下游现状和拟建雨水系统的影响,根据模拟结果进行影响评估,并提出了可行的缓解措施。

The Wong Chuk Hang subway station in Hongkong subway south island line （east part） will be located above the Wong Chuk Hang flood discharge channel. Contruction is planned to be carried out in the drought season, so there will be some risks of decreasing flood discharge section during the construction. By using two simulation softwares of Infor Works CS and MIKE 11, the hydraulic model is built to simulate the construction effects on the upstream and downstream current situation and the planned storm water system. Based on the simulation results, the effects is evaluated and the feasible alleviation measures are brought forward.
