The dynamic response of underground engineering such as tunnel and mining roadway under the action of the explosion load of oil and gas is an important basis for engineering protection design and safety evaluation.The development of dynamic numerical simulation method in line with the characteristics of oil and gas explosion is of great significance for accurately analyzing the stability of underground engineering structures such as tunnel and mining roadway under liquefied petroleum gas （LPG） explosion. In this paper，fluid computational mechanics software FLACS was used to calculate the LPG explosion load in the tunnel. Based on transient dynamic analysis software LS-DYNA，the blast impact load was applied to the tunnel lining surface，and then the dynamic response of lining structure at different distances from the explosion center was calculated.By comparing the peak value of overpressure obtained by simulation with the calculation results of the empirical formula，the coincidence between the peak value of overpressure obtained by simulation and the calculation results of the empirical formula is high，which shows that the simulation method used in this paper has good applicability for analyzing the structural response of tunnel under LPG explosion in tunnel.Based on the numerical simulation results，the variation laws of stress，displacement and velocity of lining structure under LPG explosion load were studied.The results show that the “angular structure” of the tunnel has a strengthening effect on the reflection of shock wave，resulting in the formation of stress concentration at the corresponding position and the slow attenuation of the stress wave intensity.With the increase of the propagation distance，the stress on the lining decreases gradually and the stress value of the same section tends to be consistent.In addition，the velocity and displacement values at different measuring points on the same section are affected by the distance between measuring point and explosion center and the geometric structure of the tunnel.When the distance between measuring point and explosion center is larger than 12 m，the velocity and displacement values tend to be stable.The damage of top lining and bottom structure is more likely to occur under the action of blast load，and the damage degree of sidewall position is less.The research results provide a method basis for the safety and stability analysis of underground structures，and also have a certain reference value for the anti-explosion design of mining roadway structure and the corresponding support optimization in mining.
