- W2983993054 abstract "The finite element method is used to analyze the stress and deformation of the crossing gas pipeline. The evaluation results show that the current pipeline stress and displacement cannot meet the allowable values specified in the specification. In order to ensure the safety of pipeline operation, it is necessary to treat the crossing gas pipeline. By investigating the pipeline construction period and operation period data, the deformation data collection and analysis of the pipeline has been carried out. It is speculated that the direct cause of the pipeline deformation is the temperature difference and the internal pressure and gravity. The indirect cause is that no appropriate compensation structure or sufficient restraint measures have been taken across the two ends. Cracking of the protective wall across the ends is a secondary failure of displacement. The finite element method is used to check the proposed governance measures, and finally determine more reasonable control measures. After the implementation of the treatment measures on the site, the better results were achieved. The pipeline stress and deformation were all within the requirements of the specification. The pipeline was in a safe state and the treatment measures were feasible and practical. The engineering application results show that the feasibility of checking the cross-section pipeline control measures by the finite element method has certain effectiveness and economic rationality, and can achieve the purpose of engineering governance." @default.
