ANALYSIS OF GROUND IMPROVEMENT FOR CONTROLLING
THE EARTH RETAINING DEFORMATION BASED ON THE MEASUREMENT RESULTS
F.Nakazawa, S.Miura, and T.Kitamura
In this paper, by comparing the ground deformation of ground improvement measured in the fields of performing the ground improvement for controlling the earth retaining deformation, we considered the effects of the difference in construction conditions. As a result, it was confirmed that ground deformation of the neighborhood became large under the influence of the existing building structures. Also, from the measurement result of the earth retaining deformation during excavation, by selecting a ground improvement method properly, it is confirmed that the deformation of earth retaining wall will be possible to control the during excavation.
