Stress and Deformations in Railway Track-Type Structures
Abstract
철도궤도시스템을 단순화시킨 지반위에 놓인 궤도형 구조물을 Talbot 이론 및 연속탄성 지지 모델, 2차원 Plane Strain 모델, 3차원 유한요소 입체모델 그리고 탄소성 지반위의 궤도형구조물을 기발표된 현장 실측치와 비교하여 탄성 및 탄소성 지반위에 놓인 궤도형 구조물의 해석치를 비교 검토하였다. 지반을 탄성으로 본 경우와 실상에 가까운 탄소성으로 본 경우의 수치해석 결과 하중 작용점 아래에서의 깊이에 따른 수직 처짐량이 표면에서 표면아래 50cm가지는 그 처짐량이 1.83배∼1.92배로 컸음을 알 수 있었고, 탄소성 지반위에 놓인 보에 대한 모델실험 결과와 수치해석의 결과가 거의 일치함을 확인하였다.
The study compared a Track-Type Structures on soil to make simplification Railway Track System with a Talbot theory, 2-dimensional plane strain finitemodel and 3-dimensional solid model, then compared a Track-type Structures resting on the elasto-plastic soil medium with a result of elastic and elasto-plastic analysis and field test. A result of elasto-plastic analysis was confirmed larger displacement about 1.83∼1.92 times than a result of elastic analysis, this study confirmed to correspond result of model test about a beam on the elasto-plastic soil medium with result of numerical analysis.
