안전율에 기반한 철도교대 뒤채움재 내부마찰각 영향에 따른 철근량 변화

초록

It analyzed the construction cost of reinforcement in the railway bridge abutment, changing friction angle which is important factor in the railway bridge abutment design. In this study, As the friction angle was increasing, the member force that acts on bridge abutment footing decreases. The standard of main reinforcement size used in railway bridge decreased by depending on friction angle.
