Study on the waterlogging operation effects of InfoWorks ICM dispatching strategies

Abstract

In this paper, we select the H river basin of a city in northern China as the test section of deep tunnel construction project and use InfoWorks ICM to establish a two-dimensional hydraulic model in the basin. The basin is divided into 9 subsystems from T1 to T9 for ease of research, study the waterlogging control effect of the optimal dispatching operation strategies of deep tunnel in the basin.The results show that the waterlogging control effect meets the construction target of deep tunnel project, after the drainage of deep tunnel, the rainfall recurrence period of waterlogging risk of each subsystem is increased from more than once every year to once every ten years.
