摘要
2018年8月11日13:00~17:00珠海市金湾区4h总降雨量高达351.5mm,极端降雨造成了山洪外泄,导致机场周边积水严重。采用Infoworks ICM城市流域综合模型,在模型中统筹考虑山水汇流、截洪沟截流、水库蓄水、排水管网排水、河道及外海潮位顶托,对珠海机场片区进行模拟评估,在分析机场被淹的具体成因基础上,最终提出加高截洪沟、完善雨水收集系统、扩大排洪渠、增设泵站等内涝系统治理方案,消除水浸黑点,保障珠海机场片区的正常秩序与行洪安全。
From 13:00 to 17:00 on August 11 th,2018,the total four-hour rainfall in Jinwan District of Zhuhai City reached 351.5 mm.Extreme rainfall caused mountain torrents to spill out,resulting in serious water accumulation around the airport.Based on the comprehensive model of Infoworks ICM urban watershed,this paper simulates and evaluates the Zhuhai Airport area by taking the mountain and water confluence into account,flood interception ditch interception,reservoir storage,drainage of drainage pipeline network,river course and tide level support in the model.On the basis of analyzing the specific causes of the airport flooding,the paper finally proposes to increase the flood interception ditch,improve the rainwater collection system,expand the flood drainage ditch and increase the number of flood drainage ditches.Pumping stations and other waterlogging control schemes to eliminate the black spots of water immersion and ensure the normal order and flood safety of Zhuhai Airport area.
