Numerical Simulation and its Countermeasure for Leakage and Diffusion of Gas Transmission Pipeline after Earthquake
Gas pipeline leakage and diffusion process caused by seismic disasters, the transient model for leaking gas in different diffusion links is established and the corresponding measure for numerical simulation is presented. It can delimit the areas of different disserving degree by the leaking point for center. The measures for making emergency and rush to repair on leakage accident after earthquake and establishing emergency responds system (emergency response procedure, emergency organization system and responsibility compartmentalization, emergency protection and rescue, emergency response plan, emergency state terminating) are introduced, and a assessment system of hazard for gas leaking in pipeline after the earthquake is formed. The research results provide scientific foundation for the developments of manufacture management in carrying through emergency and rush to dealing, improving ability for meeting emergency, shortening rapid repairing time, decreasing economy expense.
