摘要
长输高陡坡段管道的设计长期以来主要按照经验进行,缺乏科学判断管段是否安全的依据。高陡坡段管道是长输管道中的安全控制特殊地段,使用应力分析软件对高陡坡段管道建模并对该段管道的安装、试压、运行、特殊等工况进行应力分析,判定管道的应力在各种工况下是否符合标准、规范要求,约束点设置是否合理。在长输管道的设计中常会人为地增加锚固点,通过应力分析可准确判断增加的锚固点是否合理、有效。因此对高陡坡段管道进行应力分析是判断该段管道设计是否安全合理的有效手段。
For a long time,long-distance pipelines located in high steep slopes are designed according to historical experience and there is lack of scientific means for determining whether such designs are reasonable,it is necessary to conduct analysis on stress in long-distance pipelines located in high steep slopes so as to accurately judge whether pipeline stress meets relative requirements in codes,specifications and standards.Because pipeline sections in high steep slopes are located in special terrain,stress analysis software shall be adopted to conduct their stress analysis in installation,test and operating conditions and special conditions to determine the conformity with relative standards and specifications and check whether their constrained points meet the requirements of actual construction.Stress analysis of pipelines can also determine the reasonability and efficiency of anchorage points artificially added in long-distance pipeline design.Therefore,analysis on stress in long-distance pipelines located in high steep slopes is an effective measure to determine whether such design is reasonable.
