Abstract
In road construction, to prevent the fall of soil and wherever there is a need for lateral support for the vertical wall of excavation, a variety of retaining structures are used. Considering that against equal forces, shells are less thick than flat slabs, and as a result, their use is more economical in terms of consumables, Therefore, in this research, in order to reduce the consumption of materials, thin-walled cylindrical shells have been adapted to concrete gravity retaining walls and a new structural form has been proposed. Then a new method for calculation and analysis is provided. In this article, based on the theory of cylindrical shells and considering the physical and mathematical aspects of the problem, the governing equations of the new structure have been presented. Mathematical principles and theoretical analysis methods have been used in solving the problem of the retaining wall consisting of three concrete cylindrical shells.
