摘　　要：本文阐述了某型燃气轮机燃油管路在外场运行时出现裂纹故障,通过对其进行系统性分析,采用故障树分析方法,对各底事件进行排查,最终从失效分析、设计复查、加工复查、装配复查、使用环境复查等因素进行分析,确定故障原因为管路动应力过大以及操作不当,并提出增加支架、卡箍等解决措施。The leakage problem of the fuel pipe on a certain type of gas turbine is proposed in this report. The fault tree method is used in this paper to analyze the fuel pipe leakage problem. By investigating the bottom incident of the fault tree, the fault is finally located as the excessive dynamic stress and the improper operation. The improvement measures such as add supports and couplings are raised here.
