应用概率分析方法，提出了一种工业地上管线系统抗震可靠性分析方法。该方法可以考虑地震作用等的随机性，用概率方法给出了地上管线支架单元不同破坏状态的概率值及管道与支架连接单元的失效概率，假定支架单元和连接单元的破坏为统计独立，则可综合给出地上管线的抗震可靠性指标
Probabilistic analysis method is used to propose a seismic reliability analysis method for industrial above-ground pipeline systems. The method can consider the randomness of the earthquake action, etc., and probabilistically give the probabilistic values of the different failure states of the above-ground pipeline support units and the failure probability of connecting units between the pipeline and the support. Assuming that the damage of the support unit and the connection unit is statistically independent, Comprehensively gives the seismic reliability index of above-ground pipelines
