Analysis on Structural Characteristics of Double Reinforced Retaining Wall

Combined with the structure of double reinforced retaining wall applied in reconstruction engineering of Yuan'an-Dangyang Arterial Highway,this paper carries out analysis on its structural characteristics with nonlinear finite element method and simulates the nonlinearity of soil materials with Drucker-Prager Model to study the distribution rule of reinforced stress and wall back soil pressure along wall height.Finite element analysis result tallies closely with site measurement value.It is indicated that the structure of double reinforced retaining wall is obviously different from that of common gravity retaining wall.The result provides reference for engineering application and further promotion.
