应用InfoWorks模型对深隧入流点设置方案的优化

Optimization of Inflow Points of Deep Tunnel Intercepting Wells by Using InfoWorks Model

上海市提出了以深层调蓄隧道为外环内排水系统提标、内涝防治和面源污染控制的主要手段,规划近期实施苏州河段深层排水调蓄管道系统工程。为解决深隧进水流量控制的关键技术,以Info Works ICM为工具,分析管网系统的排水能力和深隧入流井设置方式之间的相互关系,提出了入流井的位置、数量及设置形式对系统提标和水量分配的影响,为工程系统方案制定提供技术支撑和参考。

In order to solve the problems of drainage system upgrading, urban waterlogging prevention and surface pollution control, deep tunnel has been adopted as the main way within the outer ring in Shanghai,and plans to build deep tunnel project in Suzhou River reach. In order to solve the technology of controlling influent flow of the deep tunnel, the relationship between the capacity of drainage system and the setting scheme of the deep tunnel inflow well is analyzed based on the InfoWorks ICM model. Through the study, the influence of the position, quantity and setting of the inflow well on the drainage system upgrading and the water distribution between the two systems are proposed. This study can provides technical support and reference for the design and construction of the deep tunnel project in Suzhou river.
