针对铁路运输危险气体泄漏事故的特点,文章以高斯烟羽模型为基础,借助Matlab编程对不同条件下(不同风速、不同大气稳定条件和多泄漏源等)的铁路危险性气体扩散范围进行模拟分析,实现了危险性气体扩散的直观图形表示和伤害分区的划分,为指导铁路运输紧急救援提供一定的指导作用。

A diffusion model of the characteristics of railway transport dangerous gas leakage accident was built based on Gaussian plume mode, using matlab to simulate the diffusion range of railway dangerous gas in the different conditions (different wind speed, different atmospheric stability conditions and different number of leakage source and so on). It can get direct diagram and division on damaged area of the diffusion of dangerous gas, the result can provide certain function for railway transportation emergency rescue.
