摘　　要：综合管廊燃气舱燃气泄漏后爆炸冲击波会对廊内结构造成严重的破坏。本文研究阜阳市润和路段燃气舱不同通风分区的长度、舱内高度对爆炸冲击波的影响研究,结果表明:改变燃气舱通风分区长度对爆炸峰值超压数值变化影响较小,因此通过增加通风分区长度不会增加燃气爆炸时的峰值超压;峰值超压、流速峰值及温度峰值随舱内高度增加而减小。通过研究结果,选择最合适的燃气舱高度,降低事故危害,对综合管廊燃气管道入廊有着重要的现实和指导意义。Comprehensive pipeline corridor gas cabin gas leakage after the explosion shock wave will cause serious damage to the structure of the corridor.This study investigates the impact of different ventilation zone lengths and chamber heights on the explosion shock wave propagation in the gas chamber of a section of Runhe Road in Fuyang City.The results show that changing the length of the gas cabin ventilation partition on the maximum explosion overpressure value of the change is similar,therefore,by increasing the length of the ventilation partition will not increase the maximum overpressure of the gas explosion;peak overpressure,the peak flow velocity and the temperature of the peak value of the cabin with the increase in the height and decrease.Through the results of the study,choose the most suitable gas cabin height,reduce the accident hazard,the comprehensive pipeline corridor gas pipeline into the corridor has important practical and guiding significance.
