Abstract
Retaining wall with relieving platform has advantages in terms of stability and costs because it decreases the earth pressure by installing the relieving platform. However, there have not been previous studies of the optimal design for the retaining wall with reliving platform in practice. In this study, the optimal design conditions of the retaining wall with relieving platform are proposed by evaluating the reduction effect of lateral earth pressure based on the numerical analysis of 40 cross sections by changing wall types, wall heights, shelf locations and lengths. As a result, the optimal location of a shelf is the central part of a retaining wall (h/H=0.50) and the optimal length is recommended to be designed to satisfy b/L=0.45, at least.
