Study on the Construction and Countermeasures of the Flood Control and Drainage System for Hub Airport
In response to the lack of systematic of flood control and drainage design strategies for frequent airport flood disasters,the 3 phase expansion project of Taiyuan Wusu International Airport was taken as an example,a 2D rain-water system model was established by InfoWorks ICM software to dynamically simulate and analyze the regional rainwater system before construction.The flood risk was assessed and flooding factors was identified.The results in-dicate that regional flooding is compounded by the low design standards of drainage facilities,causing a high risk of inundation in the area.Then,a systematic solution to address flood risks was proposed,including the coordination of flood prevention and drainage systems,the construction of a sponge airport,and integrated drainage and adjust-ment measures.A mathematical model of the rainwater system was constructed by SWMM software.Combined with the Python genetic and evolutionary algorithm library,single-objective and multi-objective intelligent algorithm frameworks were used to optimize key design parameters of the volume and outflow rate of retention ponds.Evalua-tion showed that the proposed construction plan meets the 50-year return period drainage and waterlogging preven-tion standard and the 100-year return period flood prevention standard,providing a reference for drainage and flood prevention system construction at other airports.
