摘要

文章对破坏性地震中可能发生的次生毒气泄漏与扩散灾害进行了数值模拟与动态仿真研究 ,设定了几种有实际意义的数值分析模型 ,分别进行了结构地震破坏、有毒有害气体泄漏、在一定泄漏和气象条件下的向周围空间扩散的动态仿真研究 ,给出了典型毒气扩散过程中可致人员死亡、严重危险和有感区域的范围的动态变化结果。作者认为地震次生毒气泄漏与扩散研究对大地震应急、城市和大型企业防灾都有重要的意义和广阔的应用前景。
In this paper, the numerical simulation and dynamic emulation of poison gas leakage and diffusion that possibly occur in the destructive earthquake are studied. Several numerical analysis models with realistic significance are supposed. Poison gas leakage and dynamic emulation of poison gas diffusions in space under certain leakage and meteorological conditions are in progress on the basis of the models. As a results dynamic variations of fatal area, very dangerous area and sensible area are given during some typical gases diffusion processes. In authors' opinion it is very important in big earthquake emergency, disaster prevention of cities and large enterprises to research on earthquake-induced poison gas leakage and diffusion. It should have wide-ranging application prospects.
