쇄석말뚝-쇄석매트로 보강된 연약지반의 지지력 특성

Recently it was difficult that good condition ground was obtained in construction works, so constructions was built in soft ground with stabilized method. Therefore stone pile method is the ground improvement method which was composed of compacted grovel or crushed stone inserted and obtained the required bearing capacity by replacing area ratio 20~30%. Therefore in this study, it was investigated the characteristics of bearing capacity of group stone piles-stone mat system and the increasing factor of bearing capacity and settlement behavior with changing the mat thickness through the laboratory model tests. Also, the model tests was compared through the finite element analysis(FEM).
