Numerical Analysis of Force and Deformation Characteristics of Reinforced Steel Corrugated Sheet Retaining Wall

Abstract Reinforced corrugated Steel retaining wall is a kind of retaining wall structure that can realize rapid construction. It has the characteristics of large strength, high rigidity, fast construction speed and small environmental disturbance. In this paper, the finite element model is established by using ABAQUS software. With the load of 80Kpa and 120Kpa at the top of the fill, the mechanical and deformation characteristics of the steel corrugated board are studied under the coupling of steel corrugated board and fill soil. The Horizontal deformation of corrugated panel and soil of different depths are analysed. Then the stability of the retaining wall structure are analysed. The research shows that the steel corrugated retaining wall presents a reverse “S” shape under the action of filling, the upper part presents an outward deformation, and the lower part presents an inward deformation extrusion soil; under the up load, the middle part of the retaining wall produces protrusions. As the load increases, the bulge increases with the tendency of the outward inclination. The stability analysis shows that the safety factor of the retaining wall structure under the load meets the requirements of relevant specifications.
