초록
The ground work with of the research is constructed by a SCP method to improve clay ground in the sedimentary layer and sand ground in the reclamation layer at the same time as a reclaimed soft ground by reclaiming deep depth. Improved fine-grained soils in the sand ground decrease the ground improvement effect and have an influence on replacement ratio of SCP method. Fine-Grained soils which advances in sand ground reduces a from improvement effect, Makes affect in replacement ratio of SCP method. In this study, consideration about replacement ratio of sand ground, Tried to observe affects in replacement ratio of fine-grained soils SCP method of dredging reclamation ground. The result, replacement ratio which follows in the Japan Geotechnical Society experience-chart(1988) recording where fine-grained soils content will increase feebly, was visible the aspect which increases progressively, replacement ratio in compliance with Gibbs and Holts(1973) methods according to fine-grained soils increase is visible the tendency which decreases gradually with the enemy. Specially, according to case fine-grained content of Mizuno(1987) methods increases, replacement ratio suddenly was showing the trend which rises from of 50% and according to fine-grained soils increase was overestimated.
