摘要
回顾了输气管道的止裂研究工作,并针对高韧性高压力管线出现的原有止裂预测模型不准确的问题,介绍了国内外各研究机构提出的改进方法。在此基础上提出研究发展趋势,旨在为现有管道建设提供一些参考。
A review is made of the research on fracture arrest of gas pipeline. In view of the inaccuracy of the original model for predicting fracture-arrest toughness of high-pressure gas pipeline, an introduction is made of the improving methods suggested by the research institutions in and outside China. On this basis, the tendency in this area is revealed so as to provide some reference for gas pipeline construction.
