- 摘要:
- 海洋管道焊接接头的疲劳性能关系到焊接结构的安全性和经济性，考虑到疲劳计算、抗疲劳设计和小尺寸疲劳试验在管道疲劳寿命评定分析中的局限性与不足，管道全尺寸疲劳试验技术越来越受重视。近年来，随着电子计算机控制的电液伺服疲劳试验技术的迅速发展，管道全尺寸疲劳试验技术也取得了很大进展。文章从海洋管道焊接结构的力学特性，英国、日本、巴西、挪威及国内海洋管道全尺寸疲劳试验技术的研究现状等介绍了该领域的发展状况，并为国内该试验技术的发展方向提出参考意见。
The fatigue performance of marine pipeline welded joints is related to safety and economy closely.Owing to the limitations and shortcomings of fatigue calculation,anti-fatigue design and small-scale fatigue test in the pipeline fatigue life assessment analysis,the full-scale fatigue test technology is paid more and more attention.With the rapid development of electrohydraulic servo fatigue test technology in recent years,the full-scale fatigue test technology has been developed greatly.In this paper,the current status and development trend of the full-scale fatigue test technology for marine pipelines are introduced with respect to the mechanical characteristics of marine pipeline welded joints and the current research status of the full-scale fatigue test technology in United Kingdom,Japan,Brazil,Norway and China.2013,4(4): 1-7 收稿日期：2013-1-18DOI：10.3969/j.issn.1001-2206.2013.04.001作者简介：胡艳华(1981-)，女，湖北荆州人，高级工程师，2009年毕业于中国石油大学(北京)，博士，现主要从事海洋结构建造安装技术研究工作。参考文献：
