【摘要】 在单体建筑火灾发生率模型的基础上,根据燃气系统的特点,引入了不同燃气设备破坏等级对火灾的影响概率系数,建立了燃气系统地震次生火灾发生率的模型。利用该模型对武汉市燃气系统的火灾发生率进行了预测,并对火灾后果进行了数值分析。根据武汉市燃气系统调研和抗震评估的结果,分析得到了武汉市燃气系统在地震作用下次生火灾的概率及可能造成的灾害后果,为城市抗震防灾规划提供了依据。更多还原

【Abstract】 This paper established the model of secondary earthquake fire incidence of gas system,it based on the model of single building fire incidence and introduced fire influence coefficient with different gas equipment according to the characteristics of gas system.The fire incidence of the gas system of Wuhan was predicted through using this model,and did the numerical analysis of fire consequence.With the survey and the seismic evaluation result of the Wuhan gas system,the secondary earthquake fire probability of gas system under earthquake and possible fire consequence was acquired through analysis,and the city planning of earthquake-resistance and hazard prevention was provide another basis.更多还原
