Stress Analysis of Buried Pipeline in Gas Transmission Station Under Uneven Settlement of Ground
When the natural gas transmission station is soft soil,it is easy to cause uneven settlement of the foundation,and the buried pipeline is easy to be damaged.In this paper,ABAQUS finite element software was used for analysis,and an integrated finite element mechanical model of pipeline and soil was established.The stress and displacement of buried pipeline under uneven settlement of foundation were analyzed,as well as the influence of settlement amount on pipeline stress,and the stress changes of pipeline under changes in pipeline wall thickness,pipeline pressure,pipeline burial depth and soil cohesion were explored.The maximum Mises stress variation rule was obtained.
