基于熵权模糊综合评价的桥梁汽车燃烧风险分析
Study on Vehicle Burning Accident During Bridge Operation Period Based on Entropy Weight Fuzzy Comprehensive Evaluation
摘要
Abstract
As the traffic flow increases, the risk of burning vehicle is higher and higher on the bridge. This paper introduced fuzzy comprehensive evaluation method to analyze the risk of vehicle burning accident. According to the principle of fuzzy comprehensive evaluation to establish comprehensive evaluation index system, using the entropy weight method to obtain the weight of various indicators of risk factors of fuzzy comprehensive evaluation, it is effectively solve the problem of weight allocation. So we established the risk analysis model of vehicle burning accident during bridge operation period based on entropy weight fuzzy comprehensive evaluation, this model was used to analyze the risk of vehicle burning on YingWuZhou Yangtze River Bridge. And it showed that tank burning accident risk level was 0. 021443 times/year, in occasional risk level; car burning accident risk level was 0. 234261 times/year, in a possible risk level; coach burning accident risk level was 0. 120771 times/year, in a possible risk level; truck burning accident risk level was 0. 042219 times/year, in a possible risk level. It could play certain reference significance for Fire design of Bridges and the preventive measures.关键词
