摘要
基于MIKE11模型的水动力模块、对流扩散模块建立了南水北调中线京石段的水质模拟模型,通过对模型的率定和验证,表明该模型具有较理想的模拟效果。在此基础上构建模拟段突发性水污染事故污染物运移扩散模型,模拟了典型跨渠公路桥上发生危险货物运输倾翻事故后污染团的迁移扩散过程,以及污染团到达下一个分水口和退水闸的时间和浓度,旨在为制定京石段干渠突发性水环境污染事故应急方案提供依据。
Based on the Hydrodynamic model of MIKE11,the water quality simulation model in the BeijingShijiazhuang Section of the Middle Route of South-to-North Water Transfer Project was established. The coefficients calibration and model verification indicated that the established model had a good simulation result. Based on that,models of pollutant migration and diffusion during sudden water pollution accident were established. The model simulated the migration and diffusion of pollutant in the open channel of the Middle Route after dangerous goods transportation accident on the bridge happening. Furthermore,the arrival time and concentration of pollutant in the next turnouts and water discharge gate were also simulated. The obtained results could provide scientific and useful information for emergency plan of sudden water pollution in the Beijing-Shijiazhuang Section of the Middle Route of South-to-North Water Transfer Project.
