Abstract
Based on the crowed places (subway stations are mainly considered), a personnel evacuation coupling model combined with fire environment is proposed in this project, and a computer simulation system is developed. Firstly, a model of personnel evacuation considering environmental factors is established based on the social force model, and the model is dispersed into particle system model by the smoothed particle hydrodynamics (SPH), namely the evacuation SPH coupling model. And then, a personnel evacuation simulation system based on virtual reality technology is developed, implementing the modules of specific personnel evacuation warning and emergency evacuation decision-making. This system can provide technical support for fire control room staff, fire management departments and policy experts.This project has important guiding significance for personnel evacuation safety analysis in the building, which can provide a reference for the establishment and application of the safe evacuation analysis method in our country, and provide theoretical basis and technical support for preventing a stampede and emergency evacuation.
