摘要:
针对CBRN事故中的毒气泄漏场景进行研究，采用SLAB模型模拟有毒气体的泄漏扩散，并给出模拟流程。以山东某企业光气泄漏灾害应急疏散项目为例，计算不同风速和泄漏孔径的毒气泄漏的最远扩散距离、到达时间与持续时间。通过模拟获得有毒气体浓度的时间空间分布数据，得出致死区、重伤区和轻伤分区的范围变化情况。证明随时间的推移，光气不断向下风向扩散。最后通过系统设计与程序运算，实现了事故信息的获取、划定事故影响区域和疏散范围以及对疏散人口进行预测的目的。有毒气体扩散模拟与区域疏散分析对于合理制定针对CBRN事故的应急疏散方案具有重要意义。
Abstract:
For gas leak in CBRN accident, the SLAB model is to used to simulated the leakage and diffusion of toxic gas, and the specific process of gas diffusion simulation is given, which can provide a basis for regional evacuation analysis. Taking the emergency evacuation project of a Shandong enterprise group in phosgene leak disaster as an example, the furthest diffusion distance, arrival time and duration were calculated in gas leak accidents with different wind speeds and aperture leak respectively. Time and space distribution data of toxic gas concentration were obtained by diffusion simulation, and then the changing of lethal area, seriously injured and slightly injured area were obtained. Phosgene was proved to spread down the wind direction continuously. Finally, through system design and procedures operation, the accident information acquisition was achieved, and the affected area and evacuation area were delineated on the road network, as well as prediction of population size of evacuation was achieved. The diffusion simulation of toxic gas and analysis of regional evacuation has great significance to in decision making of emergency evacuation plan for CBRN incidents.
