Transverse vibrations of an underground cylindrical structure

Abstract

The transverse vibrations of an extended cylindrical underground structure under the action of concentrated forces changing according to a harmonic law are considered. The problem of transverse vibrations of a cylindrical rod interacting with an elastic homogeneous medium was solved by the Fourier method. Approximate solutions are obtained using the method of compensating loads. The influence of soil conditions and geometrical dimensions of the structure, the location of active forces on the amplitude-frequency characteristics of the object are analyzed.
