摘要
Abstract
In order to timely understand the changes of the structural characteristics during the pipeline operation,the solutions that buried pipeline under the condition of nonuniform frost heaving had been drawn by the theory of beam on elastic foundation.Using ADINA,which is a finite element software,es-tablished three-dimensional model and completed the thermo-mechanical coupled analysis.Through the calculation the pipeline frost heaving force after freezing and thawing cycle,it is concluded that the influ-ences of the temperature,pipeline buried depth and transition segment length on the pipeline stress and strain,and position of the pipeline largest stress is determined.关键词
