초록

본 연구에서는 공동주택의 리모델링 시 기초보강공법의 하나인 하중전이 장치를 이용한 기초보강공법에 대해 3차원 유한요소 수치해석 연구를 수행하였다. 실대형 현장실험을 통해 수치모형을 검증하였고, 매개변수 해석을 통해 하중전이장치의 마찰계수, 말뚝의 축강성이 기초보강공법의 성능에 미치는 영향을 확인하였다. 그 결과 하중전이 장치를 이용한 기초보강공법은 보강 중, 보강 후에도 기존 말뚝에 작용하는 하중을 자유롭게 조절가능함을 확인하였다.

In this study, a numerical analysis using a three-dimensional numerical simulation was performed to assess the applicability of foundation reinforcing method using load transfer apparatus which can be used in the remodeling of deteriorated structures. The numerical model was validated through comparison with the real scale experimental results, and then a parametric study was performed to investigate the effect of friction coefficient of load transfer apparatus and axial stiffness of pile on the performance of foundation reinforcing method. It was confirmed that the foundation reinforcing method considered in this study can efficiently control the load applied to an existing foundation.
