실험적 연구를 통한 성토체의 장기거동에 따른 다짐도의 영향

초록

The main objective of this study is to investigate the effect of relative compaction on the behavior of the long-term settlement of embankment for High-seed railway. Sandy soil classified as SP-SM was collected for the test from railway construction field. Two steps of constant loading were applied for a long period. The results of consolidation test indicates that the initial condition was influenced to the final settlement. From the experiment result, the predicted settlement of embankment having 10 m height within 10 years was found that exceeding the allowable limit of residual settlement in Korea.
