Abstract
Understanding behavior of soil may contribute to design retaining walls safely and efficiently. Therefore, in this study, behavior of ground by active and passive retaining walls was compared through finiteelement analysis and laboratory model test using close range photogrammetric method. From the close range photogrammetry, deformation of sandy ground according to roughness and horizontal displacements of the model retaining wall was recorded and analyzed. The roughness was compared to interface factor. Also, vertical horizontal displacement and shear strain of the sandy ground were analyzed by PLAXIS 2D. The result of comparison between the numerical analysis and the laboratory model test shows good agreement. Consequently, the close range photogrammetry with image processing can be used to measure the ground deformation accurately. The relationship between the roughness of the wall and the interface factors can be used to design safely and efficiently.
