摘　　要：以金坛储气库为工程背景,建立该深部地下盐岩储气库的动力计算模型,在考虑深部地下地应力的情况下,讨论了地震在不同工作内压下对盐岩储气库的影响。研究表明,在高围压状况下,地震对盐岩储气库的影响较小,在一定范围内,当工作内压增大时,地震对储气库的影响程度会减小。以当地抗震设防等级等量的地震对储气库的影响在安全范围内。Based on Jintan gas storage,this article establishes a dynamic force calculation model of the deep underground gas storage cavern and discusses the effect of the earthquake on it under different internal pressure of gas storage,considering the ground stress in deep underground. The research shows that the effect of earthquake on the gas storage will be small when the gas storage cavern is under a high surrounding stress,and that the increasing internal pressure will decrease its dynamic response to the earthquake. At present,the effect of the earthquake with the same level as local earthquake fortification will remain in safe range.
