基于元胞自动机的城市地震次生火灾蔓延模型

Urban post-earthquake fire spread model based on cellular automata

根据模拟复杂系统的元胞自动机,并利用其组成,构建了城市地震次生火灾蔓延模型。通过相关参数的初步量化,模拟了某小区的火灾蔓延,得到了大面积阻火要素,如道路、公园等对阻止火势进一步蔓延的重要作用,及风对火蔓延的重要影响,又考虑了消防扑救对控制火势蔓延的影响,为城市规划和震后火灾扑救提供参考。

Based on the cellular automata simulating complex system and its components, an urban post-earthquake fire spread model was constructed. By initial quanlization of relative parameters, the fire spread in a substrict was simulated. The importance of fire-resisting elements of large area, such as roads and parks in resisting fire spread and the influence of wind speed on fire spread were pointed out. The effect of fire protection and fighting on control of fire spread was considered. The results can give a reference to urban planning and post-earthquake fire fighting.
