摘要:
为分析地铁上覆管道爆炸对乘客安全影响，采用基于超压冲击波阀值数值模拟，通过将泄漏气体能量等效为TNT当量，分析不同泄漏模式爆炸冲击波对地铁隧道及人员安全影响。结果表明：爆炸产生的超压冲击波对隧道及人员影响小于限值，不会造成人员伤亡，研究结果可为地下工程下穿油气管线安全影响分析提供理论支撑。
Abstract:
In order to analyze the influence of subway overlying pipeline explosion on the safety of subway tunnel,a numerical simulation method based on the threshold value of overpressure shock wave was proposed.By equating the energy of leakage gas to the equivalent of TNT,the influence of the leakage and explosion of highpressure gas pipeline on the safety of subway tunnel and personnel in tunnel was analyzed.The results showed that the influence of overpressure shock wave generated by the explosion on the personnel in tunnel was lower than the limit value,and it would not cause the casualties.This method and conclusion can be applied in the safety influence analysis of underground engineering undercrossing the oil and gas pipelines.
