摘要:

本文对跨越深谷或河流的悬垂管道,考虑到它具有一定的刚性,用微分算子法求解,再根据边界条件确定其挠度曲线方程和弯矩方程,从而求出悬垂管道的内力和变形,并用实例将悬垂管道与柔性悬索作了对比。


Abstract:

In this paper, suspended pipelines with definite rigidity which cross over deep valleys or rivet's are studied by the method of differential operator. According to boundary conditions, the equation of flexibility and the equation of bending moment are determined. And then the internal stress and deformation of the suspended pipelines are obtained. An example is used here to compare with the flexible suspended cables.
