유한요소해석을 이용한 2차원과 3차원 성토지지말뚝 모델의 말뚝 응력비 비교 연구

초록

Recently, piled embankment system has emerged as an appropriate method to achieve strict settlement criteria for concrete slab track on the soft ground in Korea. The piled embankment has constructed to transfer the train and embankment load to the bearing layer through the piles. During the load transfer, vertical load on the soft soil decreases due to the appearance of the soil arching phenomenon. In this paper, 2-D and 3-D piled embankment models have developed to compare the column stress ratio between the soft ground and pile caps depending on the supporting type of piles.
