Abstract
The numbers of construction cases with self-standing steel pipe pile retaining walls in soft rock are now increasing in Japan. However, the current design method to determine the necessary embedment length in such a case is empirical, not theoretical and reasonable. In this study, rigid plastic FEM was used to simulate the result of centrifugal model tests aimed to establish a rational design method of self-standing steel pipe pile retaining wall and examine the validity of the analysis. Furthermore, the impact of the stability with shortening of embedment length was evaluated by the same methods. As a result, the validity of this analysis method is confirmed and the effect on the safety factor due to the shortening of the embedment length can be quantitatively estimated.
