This study was conducted to investigate by experiment changes in the horizontal earth pressure that acts on the retaining wall surface and then examine the effect of soil improvement on uniformly distributed load on the ground surface. The results of this study are summarized below. (1)In any of the cases of soil improvement, the earth pressure that acts on the surface of the retaining wall falls significantly several days after ground preparation. (2)When soil improvement is done, no horizontal earth pressure with uniformly distributed load on the ground surface acts on the retaining wall surface at the improved part of the ground. (3)The wider is the range of soil improvement(θ), the smaller is the amount of the horizontal displacement of the retaining wall with uniformly distributed load on the ground surface.
