도시철도 콘크리트궤도의 구조 건전성 평가를 위한 매개변수 연구

Abstract

In this study, the parameter for setting up the structural integrity evaluation and diagnosis system of concrete track structure on the serviced urban transit was produced by precision safety diagnosis system for civil structure. The finite element analysis was performed by FE model for concrete track with consideration for elastic materials of track components. The rating factor and the adjustment factor were investigated and comparing and analyzing with the result of field measurement. The track adjustment factor was investigated by analyzing the track impact factor based on variation of track support stiffness and dynamic wheel load fluctuation for structural integrity evaluation for track structure, and track adjustment factor was applied to the load carrying capacity evaluation for track structure. As a result of this study, the evaluation system of load carrying capacity and structural integrity for concrete track was proposed with consideration for the track condition of serviced urban transit.
