布达拉宫古建筑的火灾风险分析

利用火灾风险分析的方法对具有重要历史和文物价值的布达拉宫古建筑进行安全评估。以建筑自身状 况、着火源控制、消防设施配备、人员疏散设施以及消防安全管理等方面的现状为切入点,对布达拉宫重点区域 作了火灾危险性调查。在此基础上,引入半定量的火灾风险分析方法,分析影响布达拉宫古建筑火灾风险水平的 各因素。对体现火灾风险重要性的各参数划分等级并对其进行赋值。通过计算布达拉宫古建筑部分重点区域的火 灾风险值,分析不同区域的相对火灾风险水平。最后提出一些火灾防治的对策。

Fire Risk Evaluation for Historic Building of The Potala Pal ace

The Potala Palace was built in the 7th century and it is famous for its great historic and cultural values. From the aspects of fire resource, equipment of fire fighting, evacuation of people and management of fire safety, the situation of fire hazard was investigated in detail. It is necessary to have an efficient approach to evaluate older buildings of significant historic values. Fire risk evaluation described in this paper is one kind of semi-quantitative methods. It uses a model of multiple attribute evaluation to produce a measure of relative fire risk. Weights are established to indicate the importance of fire risk parameters. Then, for each specific historic structure, parameter grades, i. e. , the amount or degree that a parameter is present, are determined from information collected in the actual situation of the survey. Fire risk is evaluated by the scalar product of the parameter weights and grades, producing a single numerical value representing the level of fire safety provided in the building. Moreover, suggestions are given about fire prevention and protection.
