Planning Strategy of Flood Control and Drainage in Jinan Airport Economic Zone
In order to clarify the reason of waterlogging in Jinan Airport Economic Zone,to ensure the drainage safety of expansion and key areas,the paper explores the main factors affecting waterlogging,and build a regional water network system.By analyzing the regional water network system of the current topography in the area,the investigation was conducted on the current demands of river course and airport discharge,as well as the implementation of territorial spatial planning conditions.SWMM software was used to dynamically prove that uneven rainfall in time and space of water network system,flat and low-lying terrain,and poor drainage were the root causes of high waterlogging risk in the zone.Vertical optimization and dike strengthening measures could reduce the impact of external flooding.To meet the demand of drainage outside the airport,it optimized the layout of the water network,and set the storage space,which can reduce the risk of waterlogging in the area.SWMM simulates the waterlogging risk of high river,put forward corresponding measures to solve the problem of waterlogging in flat areas.
