Abstract
In order to research the pipeline changes of structural characteristics under the seismic action during operation in permafrost region,three-dimensional model was established for the dynamic response analysis by finite element software in non-uniform frost conditions.And the effects of internal pressure,buried depth of pipe,length of transition section,length of frost heaving section,diameter of pipe and thickness of wall on stress and strain of pipeline were obtained.The results are shown that with the increase of frost length,the trend of increasing at first and then decreasing of the maximum value of the axial stress of the pipeline is shown,and the maximum stress tends to be stable,and the influence of internalpressure on pipeline is mainly reflected in the stress.关键词
