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.
