上海东站施工期雨水排水影响分析

Analysis of Impact of Rainwater Drainage during Construction Period of Shanghai East Railway Station

摘要:

妥善解决大型工程施工期雨水排水出路是保障工程顺利施工的重要前提。以上海东站为例，采用河网水动力模型进行了多方案计算，从除涝高水位及高水位持续等角度分析了工程场地雨水临排对周边区域的影响，并提出了消除其影响的相关措施，明确了临排出路。结果表明：临时排水会对周边区域带来一定的防汛压力，应通过多方案比选确定临排出路，并采取科学合理的措施消除影响。

Abstract:

Properly solving the rainwater drainage outlet during the construction period of large-scale projects is an important prerequisite to ensure the smooth construction of the project. Taking Shanghai East Railway Station as an example, the hydrodynamic model of the river network is used for the multi-scheme calculation to analyze the impact of rainwater drainage of the engineering sites on the surrounding area from the perspectives of high water level and high water level persistence of waterlogging drainage. And the relevant measures to eliminate the impact are proposed, and the temporary discharge route is clarified. The results show that the temporary drainage will bring a certain flood control pressure to the surrounding area. The temporary drainage route should be determined through multi-scheme comparison, and the scientific and reasonable measures should be taken to eliminate the impact.
