Steel-Composite Design of Railway Arch Bridge Improves Constructability Efficiency

摘要

Anjikhad River Bridge is a 372-m (1220-ft) long railroad bridge in a remote location in Katra, India. The proposed bridge has a 265-m (870-ft) arch span over the 200-m (650-ft) deep gorge. It is designed to carry a two track rail road being built as a part of a large scale railway expansion project in this mountainous area forming the Himalayan foothills. The remote project location is inaccessible and temporary access roads that meander along the mountain slopes are being built for the transportation of construction equipment and material. The design-build team proposed a steel-composite design for the arch rib to improve the serviceability, maintainability and constructability.
