Abstract

This study analyzed the effect of performance connected-type foundations of behavior and the connected beams according to the characteristics into soft clay transmission tower foundation. For this purpose, the finite element analysis model was built and connected to the transmission tower foundation mat and the contact area of the connection beam by the percentage change in the behavior and resistance characteristics were analyzed and finite element verification of the validity of the analytical model was conducted using connected-type transmission tower results of the model experiments constructed, and effective connected-type transmission tower basis of the behavior of connected beams were selected by analyzing the effect due to the increase of the stiffness. In addition, weak analysis by connected beam self-bending moment distribution was conducted.

본 연구에서는 연약점토지반에 근입된 송전철탑 기초를 대상으로, 기초부보강공법의 하나인 연결형 기초 형식의 거동과 연결보 특성에 따른 성능발휘 효과를 분석하였다. 이를 위해 유한요소 해석 모델을 구축하였으며, 송전철탑 기초에 연결보의 매트와 닿는 면적비율변화에 의한 거동 및 저항력 특성을 분석하였고, 송전철탑 연결형 기초 모형실험 결과를 이용하여 구축된 유한요소 해석 모델의 타당성의 검증을 실시하여 다양한 매개변수 해석을 통해 연결보의 강성 증가에 따른 효과를 분석하여 송전철탑 연결형 기초의 거동에 효과적인 연결보의 강성을 선정 하였다. 또한, 연결보 자체 휨 모멘트 분포를 확인하여 취약부 분석을 실시하였다.
