中文摘要：隆起屈曲是覆土管道在热膨胀的轴向压力作用下产生的弹塑性形变现象,表现为管道发生弯曲和拱出地面。管道隆起屈曲现象不仅发生在海底管道,在陆上油气田生产领域也经常发生。裸露的管道会在油气田中构成重大的安全和环境危害,因此隆起屈曲现象引起了石油工业技术人员的持续关注。结合同海外油气田外方业主及著名工程设计公司的项目合作经验,介绍海外油气田工程建设中常用的OTC6335理论、Shell DEP理论、K Peters理论中的管道隆起屈曲实用计算方法并加以实例说明,以期对海外陆上油气田工程设计及施工起到一定的借鉴指导作用。

英文摘要：

Upheaval buckling is a phenomenon of instability of buried pipelines under the influence of axial compressive force due to thermal expansion, causing elasto-plastic deformation represented by pipeline bending andarching-out the ground. The upheaval buckling of pipelines not only occurs naturally for offshore pipelines, but alsohappens ononshore pipelines of oil and gas production fields.As the exposed pipelines pose major safety & environment hazards in oil & gas fields, upheaval buckling has attracted constant attention by technical professionals from petroleum industry. Pipeline Upheaval Buckling Calculation Report is one of the most prime reports required by foreign clients of overseas oil and gas field projects. Combining the experience of cooperation on overseas oil and gas field projects with overseas clients and renowned engineering design consultants, three practical pipeline upheaval buckling calculations theory used in overseas oil and gas field engineering construction such as OTC 6335 papers, Shell DEP 31401016 and Dr. K Peters’ 2006 papers were introduced and illustrated with actual examples, with a view to playing a guiding role in the engineering design and construction of overseas onshore oil and gas fields facilities.
