Potential Risk Analysis of Urban Post-earthquake Fire Based on Attribute Interval Recognition Theory
摘要
Abstract
For the influence factors' complexity of the urban post-earthquake fire,theory about the attribute interval recognition is proposed for the potential risk analysis of urban post-earthquake fire.Firstly,an attribute interval recognition model is established to eliminate all kinds of uncertainty to maximize based on the principle of maximum entropy;Secondly,the evaluation index system for the urban post-earthquake fire was presented in terms of urban disaster hazard,exposure and vulnerability of disaster bearing body and disaster prevention and mitigation capability.Meanwhile,the grading standards of evaluation index are also given;finally,potential risk analysis for a city's post-earthquake fire is provided to validate and prove its efficiency and feasibility by the evidence theory and attribute interval recognition theory.The results show that the middle and higher risk area reaches 50.20%,61.00% and 64.90% respectively when Ⅵ,Ⅶ,Ⅷ degree earthquake occurs.The application of attribute interval recognition and evidence theory for potential risk assessment of urban post-earthquake fire were verified,which improved the stability and reliability of the risk assessment results,to provide a measurable and achievable approach for the potential risk assessment of urban post-earthquake fire.关键词
