摘要
输气管道跨越小型的河流、沼泽、湖泊、山谷、冲沟等自然障碍物或人工构筑物,可以采用单管直接跨越,根据具体的情况,单管直接跨越可又分为两类:有固定墩的跨越和无固定墩的跨越。利用有限元分析软件ANSYS分别模拟在有固定墩和无固定墩情况下管道的应力的分布和产生的应变,为跨越工程设计和施工提供理论参考。
Gas pipeline across the river,swamps,lakes,valley,gully small natural obstacles or artificial structures,can be used single pipe stride across.According to the specific situation,single pipe stride across can be divided into two categories:with fixed piers and without fixed piers.Using finite element analysis software ANSYS to simulate the strain and stress distribution under the conditions with fixed piers and without fixed pier.Provide a theoretical reference for the crossing engineering design and construction.
