摘要
长输管线跨越段立管及弯头部位管壁皱折产生对管线安全运行具有不利影响。按结构分析方法建立了斜拉柔索支承跨越段力学模型,提出了柔索非线性结构性能处理方法及数值实施方案,并用于实际工程结构分析。所提出的方法可用于工程应用参考。
The buckling phenomenon in pipe wall, which is found in the riser or elbow of the spanning part located in long distance oil pipeline, is a danger to safe operation The analysis model outlined by the article was built for the structure supported by inclined flexible cable The numerical method is suggested for nonlinear behavior about flexible bearer cable The results show that the linearization method can be applied to engineering operation
