초록

최근 국내에서 활발히 적용되고 있는 LRFD 설계법의 합리적인 적용을 위하여 상대적으로 사례가 부족한 인발하중 및 수평하중의 연구를 위하여 사회적으로 중요한 구조물인 송전철탑의 기초 형태를 바탕으로 한 원형기초를 풍화토 단일지층과 풍화토, 풍화암, 연암으로 구성된 혼합지층에서의 현장실증시험을 수행하여 인발하중 및 수평하중에 대한 각 지층의 저항성 분석을 통해 설계에 영향을 미칠 수 있는 인자에 대하여 연구하였다.

For the rational application of LRFD, which is actively applied in Korea, for the study of the pull-out load and the horizontal load, which are insufficient examples, a circular foundation based on the transmission tower foundation, which is a socially important structure, through field tests in single and mixed layer. Factors that can affect the design were studied by analyzing the resistance of each stratum to pull-out and horizontal loads.
