深层隧道与浅层管渠排水系统调度策略研究

Research on Scheduling Strategy of Deep Tunnel and Shallow Drainage System

基于InfoWorks ICM建立东濠涌(D涌)流域排水水力模型,将深层隧道与浅层管渠排水系统视作一个大排水系统,采用设计降雨输入到模型当中进行多工况模拟研究。通过静态关联液位控制方法将多个闸、泵控制液位归一于在线监测点液位,采用监测点临界控制液位控制闸、泵开启和关闭,以保障调度策略的稳定和可靠。通过评价调度策略下的D涌流域内涝、溢流污染控制效果,进一步验证模拟得出的运行调度策略的可靠性,旨在利用此调度策略保障深隧充分发挥减少内涝和溢流污染的工程效能,并为其他复杂排水系统的调度策略研究提供借鉴。

The integrated drainage hydraulic model of Donghaochong watershed was established based on InfoWorks ICM.The deep tunnel and shallow drainage system were regarded as a large drainage system,and the design rainfall was put into the model for multi-condition simulation research.The control levels of multiple sluices and pumps were normalized to the liquid levels of online monitoring points through the static associated liquid level control method,and the critical control liquid level was adopted to open and close the sluice and pump,so as to ensure the stability and reliability of the scheduling strategy.The reliability of scheduling strategy was verified by evaluating the control effect of waterlogging and overflow pollution with optimal operation strategy.So that it could be used to guarantee the engineering efficiency of deep tunnel for reducing waterlogging and overflow pollution,and to provide technical reference for scheduling strategy research of similar complex drainage system.
