In this paper, a finite element model for the analysis of the pipelinesuspensionbridge was set up with considering the initial internal force and verticality of the staying cable.
本文建立了悬索管桥分析的有限元模型，并考虑了悬索管桥恒载产生的初始内力、拉索垂度等几何非线性因素。

Compared with ordinary suspensionbridge, pipelinesuspension bridge's stiffness is smaller, wind-induced vibration problem is more prominent.
与普通悬索桥相比，管道悬索桥刚度更小、风振问题更突出。

With its beautiful appearance, long span, good economic indicators, the advantages of mature design and construction, suspensionbridge has been widely adopted for oil and gas pipeline bridge.
