반복되는 침하보정곡선상에서의 차량 주행안전성 및 승차감 평가

Allowable residual settlement of concrete track roadbed is about 30mm according to Korean design criteria of railway construction. However, when settlement length is longer, residual settlement is being allowed up to 60mm as an exception. If the settlement length is smaller, original coordinate repair is based upon the principle, while maintenance curve can be applied in case of the longer settlement in the maintenance plan. In this paper, running safety and ride comforts for high speed railway were evaluated in the place which have repeated wavelength and relatively high gradient in order to analyze the effect of correction curve gradient.
