Abstract
The displacement and deflections of reinforced pipeline supports with cellular (hollow) walls are estimated. The investigated pipeline is constructed from a spiral tube. The pipe is divided into finite circular closed cylindrical shells of a certain length, at the ends of which elastic supports having the appropriate stiffness are located. The theory of anisotropic cylindrical shells is used. By the equations of the linear theory of anisotropic cylindrical shells, the averaged components of the displacement vector are determined. An appropriate system of differential equations is derived in order to establish displacements. The solution of these equations is presented in the form of double trigonometric Fourier series. In this case the normal ground resistance of the pipeline burial is taken into account. As a result, numerical calculations of displacements and deflections of the cellular pipeline are carried out.
