| Based on the previous studies proposed by many researchers about the evaluation method of replacement depth, a modified formula which incorporates the effect factors such as embanked height and load, replacement depth, cohesive force of original ground and unit weight of embankment etc, was suggested in this study. The new proposed formula was applied in the three construction sites of Kwangyang-Bay Area (Yeocheon, Youlchon, and Kwangyang) constructed by the compulsion replacement method. The application of the new method was investigated through these case studies in domestics. A modified bearing capacity parameter was estimated form the relationship of modified embankment loading and ultimate bearing capacity resulted from the site investigation, and the replacement depth was predicted by using this parameter. In addition, through the relationship analyses between each effect factors to the replacement depth in two areas, Yeocheon and Youlchon, an empirical prediction method which can evaluate the replacement depth in adjoining area was proposed. The predicted value obtained by new method is approximately similar to the measured replacement depth in Kwangyang area. |
