| 摘 要： | 海底管道是海洋石油开发的重要设施之一，对其进行断裂安全评估是非常重要的。介绍了结构失效评估图（FAD）技术，详细阐述了BS7910：1999规范中三个不同等级的断裂评估方法和疲劳评估方法。通过断裂评估方法，能够对不向受力状态下的含焊接裂纹管道进行断裂评估，得到管道任何位置的极限裂纹长度；通过疲劳评估方法，能够对受复杂动荷载的含焊接裂纹管道进行疲劳评估，得到管道在此种受力环境下的疲劳寿命。

| Abstract: | Submarine pipeline is one of the important facilities of marine oil development. It is very important to make a fracture safety assessment on it. In this paper, the application of failure assessment diagram(FAD) technology, the fracture safety assessment of three grades and the fatigue assessment included in the BS7910:1999 Standard are introduced in detail. With the fracture assessment method, we can make a fracture assessment on the flawed pipeline under stresses, and achieve the maximum length of the flaw in the pipeline. With the fatigue assessment method, we can make a fatigue assessment on the flawed pipeline under dynamic stresses, and achieve the pipeline's fatigue life. |
