초록
This study aims to develop the program for design of a reinforced earth retaining wall. For this purpose, the external stability such as overturning, sliding andbearing capacity and the internal stability such as pull-out failure and tensile rupture of the reinforced earth retaining wall with the reinforcement spacing andthe backfill inclination were examined. In addition, the calculated results from the developed program were verified by comparing with the simulated resultsbased on the three-dimensional finite element analysis. It is expected that this program contributes to effective design of the reinforced earth retaining wall.
