    Abstract: The pipeline is one of the most important transportation tools of oil and natura l gas resources, and its anti-fracture property essentially influenced on safety of the whole pipeline transportation system. It is the scientific insurance for the safe operation of pipeline system to conduct the computer aided assessment o f oil pipeline fracture behavior. In this paper, the study on computer aided fra cture assessment of oil pipeline girth welds is carried out by means of assessme nt system developed by the authors. The research shows that the factors such as fracture toughness, mismatch between base metal strength and welding metal stren gth, and the initial crack condition are essentially effective on the fracture a ssessment of oil pipeline girth welds. The results provide a scientifically dire ctive for fracture assessment of oil pipeline.
