分析了高层建筑火灾风险评估方法的优缺点,将证据理论引入到高层建筑火灾风险综合评估的领域,提出了基于证据理论的高层建筑火灾风险综合评估模型。对专家评判中由于主观性所造成不确定性的问题,笔者采用可靠信度及信度的融合方法对其展开了分析,从而实现了对高层建筑火灾风险系统的模糊性和未知性信息的综合研究。引用实例将该模型和传统的模糊综合评估模型进行对比,结果表明,基于证据理论的高层建筑火灾风险综合评估模型具有一定的可行性和优越性。
The advantages and disadvantages of fire risk assessment methods for high-rise buildings are analyzed. Evidence theory is introduced into the field of comprehensive assessment of fire risk in high-rise buildings. A comprehensive risk assessment model for high-rise buildings based on evidence theory is proposed. In the judgment of experts, due to the uncertainty caused by the subjectivity, the author analyzes it with the fusion method of credible reliability and reliability, so as to realize the synthesis of the fuzziness and the unknown information of fire hazard system of high-rise building the study. The example is compared with the traditional fuzzy comprehensive evaluation model. The results show that the comprehensive evaluation model of fire risk of high-rise building based on evidence theory is feasible and superior.
