Against possible secondary disasters under an earthquake, the reliability analysis of gas pipelines under an earthquake is of great significance. In this paper, the axial stress generated by seismic wave propagation, the corrosion models and the pipes' characteristics are analyzed to derive a limit equation of gas pipelines' reliability for the earthquake evaluation. The probability of reliability is evaluated by Monte Carlo method. An analysis on Huainan's gas pipelines shows that the seismic axial stress in the pipeline mainly comes from the peak surface velocity; the seismic and corrosion damages to the gas pipeline are serious; due to the extended impact region of seismic wave propagation, a comprehensive analysis of the two factors is of great significance; the reliability of corrosion water supply pipeline can be effectively enhanced by reducing the variations of the pipe's yield strength, working stresses and other parameters. From an analysis of relative importance of various variables, it is concluded that the wheel load in traffic, the impact factor and the bending moment coefficient are the most important for pipeline

articleAbstract=城市腐蚀燃气管道是震后恢复中重要的生命线工程之一，因此对腐蚀燃气管道在地震条件下的可靠性分析具有重要的意义。根据地震波传播产生的轴向应力和腐蚀应力模型，建立了城市腐蚀燃气管道可靠性评价的极限状态方程，采用蒙特卡罗方法模拟了管道的失效概率。由淮南市燃气管道案例的分析结果发现，地震对管道产生轴向应力作用主要归因于峰值地表速度；地震和腐蚀作用对燃气管道的破坏作用较为严重，并且因地震波传播的影响区域很大，对两种因素进行综合分析具有重要意义；减小管材屈服强度、工作压力等参数的变异程度，能够有效地增加腐蚀燃气管道的可靠性；由管道安全的变量重要性分析，得出交通荷载、影响系数和弯曲惯量系数对管道安全最为重要。,
