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. 1. 서
