수치해석을 통한 콘크리트궤도 하부 강화노반의 적정성 검토
Appropriateness Evaluation of Reinforced Subgrade beneath Concrete Track through Numerical Analysis
초록
An active application of concrete track is being expected for the future constructions of Korean railroad. For the successful concrete track construction in earthwork areas, proper reinforced subgrades, which effectively distribute train loads to subground, should be installed. In this paper, behaviors of concrete track on the reinforced subgrade with the standard stiffness and depth were investigated through numerical analyses. The appropriateness of the reinforced subgade was evaluated by analyzing the distributions of the settlements and vertical stress beneath the concrete slab.
