FREE VIBRATIONS OF RETAINING WALLS COMPRISED OF REINFORCED ORTHOTROPIC CYLINDRICAL SHELLS IN CONTACT WITH SOIL

摘要

This paper describes a study of the dynamic strength characteristic-the natural vibration frequency of a retaining wall comprised of two orthotropic cylindrical shells reinforced by discretely distributed annular rods. The problem is solved using the Hamilton-Ostrogradsky variational principle. A frequency equation is constructed, its roots are determined, and their dependence on the physical and geometric parameters of the problem is investigated.
