摘要
为分析影响电力电缆隧道火灾风险的关键因素,从火灾发生可能性和火灾后果两方面构建了电缆隧道火灾风险因素的层次分析模型,并考虑到因素识别时可能存在的模糊性和随机性,提出了一种基于三角模糊数的层次分析法(TFN-AHP)和熵权法相结合的指标权重计算方法。对电缆隧道火灾风险影响因素的识别表明:电缆燃烧属性、电缆敷设情况和电力故障是威胁电缆隧道消防安全的重要因素。
In order to analyze the key elements that affect the fire risks in the cable tunnel,the fire risk hierarchy model of cable tunnel is constructed from the two aspects of fire possibility and fire consequence.Considering the fuzziness and randomness that may exist in the process of factor identification,a method integrates TFN-AHP and entropy weight method is proposed to calculate the weight of the factors.According to the identification of fire risk factors in cable tunnel,cable burning property,cable laying condition,and electric fault are the important factors that threaten the fire safety of cable tunnel.
