摘要:
为研究地下综合管廊燃气舱结构形式对燃气爆炸超压的影响，采用数值模拟的方法，改变燃气舱高度，通风分区长度和局部开口大小，分析不同情况下的燃气爆炸超压变化规律。结果表明：冲击波传播速度随燃气舱高度的增加而减小，随着高度的增加，超压峰值曲线由“驼峰状”逐渐变为两端高中间低的“盆形”，爆炸过程产生的最大超压与高度成反比关系。超压峰值在340 m处接近0 kPa，延长通风分区并不会增加超压峰值，可以在考虑防火的要求下根据实际情况适当延长通风分区的长度。局部开口的存在使得爆炸气流能够自由泄压，超压峰值与开口的大小成反比关系。
Abstract:
In order to study the influence of the structure form of gas compartment in the underground utility tunnel on the overpressure of gas explosion,the numerical simulation method was adopted to analyze the change laws of gas explosion overpressure under different conditions by changing the height of gas compartment,the length of ventilation section and the size of local openings.The results showed that the propagation velocity of the shock wave decreased with the increase of the height of gas compartment.With the increase of the height,the peak overpressure curve changed gradually from “hump-shaped” to “basin-shaped”,which was high at both ends and low in the middle.The maximum overpressure generated in the explosion process was inversely proportional to the height.When the peak overpressure was close to 0 kPa at 340 m,the extension of ventilation zones would not increase the peak overpressure,therefore,the length of ventilation zones could be appropriately extended according to the actual situation under the requirements of fire prevention.The existence of local openings enabled the explosion gas flow to release pressure freely,and the peak overpressure was inversely proportional to the size of the openings.
