부산신항 연약지반에 적용된 PBD공법의 지반개량효과

In this study, for soil improvement was investigated using gauge monitoring, several site investigations and additional field tests. The feed-back analysis based both on the in-situ measured values of the settlement of the embankment and on the soil properties of soft clay under the embankment was carried out. The feed-back analysis was performed with the TCON program which has generally been used to estimate the average degree of consolidation and the final settlement of the soft clay under surcharge loading. The result of CPT around soil improvement shows that the strength increased regularly with depth. As a result, this study attributed to store up the practical reference data for design and analysis of PBD improvement method, adoption of improvement methods and control of settlement for soft ground.
