EARTH-RETAINING WALL DESIGN METHOD
To provide an earth-retaining wall design method that can precisely assess feasibility of the structure easily.SOLUTION: An earth-retaining wall design method of this invention is for an earth-retaining wall 1 in which a designated horizontal direction is its longitudinal direction D1 as expressed in a horizontal section. The earth-retaining wall 1 comprises: a first earth-retaining material 2, which has concavity parts 2a recessing outwards from the inner face and convex parts 2b protruding inwards from the inner face, both alternately continuing along the longitudinal direction D1; a second earth-retaining material 3, which is separated from the first earth-retaining material 2 with a specific distance L in the width direction D2 perpendicular to the longitudinal direction D1, and which has concavity parts 3a recessing outwards from the inner face and convex parts 3b protruding inwards from the inner face, both alternately continuing along the longitudinal direction D1; and an internal ground 4 that is formed by improvement in the separation space between the first earth-retaining material 2 and the second earth-retaining material 3. The earth-retaining wall design method comprises: a study step of the elastoplasticity beam-spring model which studies the earth-retaining wall 1 with the elastoplasticity beam-spring model; a study step of the elastoplasticity FEM model which studies the earth-retaining wall 1 with the elastoplasticity FEM model; and a structure feasibility confirmation step which confirms feasibility of the structure of the earth-retaining wall 1 based on the study of the elastoplasticity beam-spring model and the study of the elastoplasticity FEM model.SELECTED DRAWING: Figure 1
