【Abstract】 In this paper, the main parameters of poison gas’s numerical simulation are analyzed on the basis of studying of the numerical simulation and dynamic emulation of poison gas leakage and diffusion possibly occurring in the destructive earthquake. Several cases are supposed, and then making use of the data and figures of poison gas’s numerical simulation in these cases, the parameters in the process of poison gas diffusion are described. The authors further verified the accuracy of simplistic models used in the numerical simulation of poison gas diffusion. It is very important in earthquake prevention and disaster decrease for cities and large enterprises to research the earthquake-induced poison gas leakage and diffusion.更多还原
