Finite Element Analysis of Track-Type Structures Resting on Elastic Soil Medium
Abstract
철도궤도시스템을 단순화시킨 평행선의 길다란 빔을 '궤도형 구조물'( Track-type structures)이라 정의하고, 본 논문에서는 궤도형 구조물 아래의 지반 거동을 3차원의 입체모델, 2차원의 plane strain 유한요소 모델로 수치실험을 하고 기발표된 Talbot 이론과 Kansas Test Track 현장실험과 비교 분석하였다. ?穉′漫? 및 실험분석 결과 궤도형 구조물 해석에서 plane strain 모델이 유용하며 나아가서 철도궤도 해석에도 적용됨을 확인하였다.
Track-type structures are defined long beams of two parallel lines on elastic soil medium. In this study, the soil behavior under Track-type structures was analysed by 3-dimensional solid model and 2-dimensional plane strain finite model. The analysis was compared with the results of Talbot's theory and Kansas Test Track.

Results of numerical analysis and model tests showed that the plane strain model was effective in solving Track-type structures. It was also confirmed that the plane strain model was applicable to the analysis of Railway track system.
