村寨建筑群火灾蔓延风险简化评估方法

Simplified assessment method of fire spread risk of village buildings based on network model

针对火灾蔓延模拟工作量大、对防火构造考虑不充分等问题,结合云南勐卡老寨的火灾蔓延风险评估,提出了一种基于网络模型的村寨建筑群火灾蔓延简化分析方法。该方法通过现场勘查和简化计算确定建筑火灾向周边蔓延的路径,建立建筑群火灾蔓延网络的邻接矩阵,进一步结合网络节点遍历算法确定出不同火灾场景下的蔓延范围,在此基础上分析了不同火灾场景、不同区域的火灾蔓延风险。

In view of the heavy workload of fire spread simulation and insufficient consideration of fire prevention structure,this paper proposes a simplified analysis method of fire spread of village buildings based on network model combined with the fire spread risk assessment of Mengka Village in Yunnan Province. Based on the field investigation and simplified calculation of Mengka Village, this method determines the path of building fire spreading to the surrounding area, establishes the adjacency matrix of building fire spreading network, and further determines the spreading range of different fire scenarios combined with network node traversal algorithm. On this basis, the fire spreading risk of different fire scenarios and different areas is analyzed.
