Evaluation of Settlements and Vertical Stress of Reinforced Subgrade of Conventional Railroad through Numerical Analysis

수치해석을 통한 일반철도의 강화노반 침하량 및 수직응력 평가

The reinforcing subgrade has the many advantages to maintain the quality of ballast track. It has also the function to prevent the softening of subgrade by mud-pumping. Therefore, active application of it is being expected for the future constructions of Korean railroad. In this paper, behaviors of the reinforced subgrade applied to conventional railroad were investigated through 3-D numerical analyses. The applicability of the reinforced subgrade to conventional railroad was evaluated by analyzing the distributions of the settlements and vertical stress of reinforced subgrade.
