Abstract
Generally, the retaining wall is becoming unstable as the height is higher. On the other hand, the retaining wall with the relieving platform is more stable and more economical than any other type of retaining wall, because the relieving platform the reduce the lateral earth pressure. In this study, numerical analyses were carried out for 15 cases varying with the type of retaining wall, length and location of the relieving platform and the backfill type. From the numerical analyses, the reduction of the lateral earth pressure was checked and the results of numerical analyses were compared with that of model tests and theoretical equations. As the results of this study, the lateral earth pressure of the retaining wall with the relieving platform is considerably less than that of cantilever wall. And the of magnitude of the lateral earth pressure is affected by the length and location of relieving platform and the backfill type.
