The structure type of the No. 3 Ulanmulun River Bridge in Ordos City adopts a landscape arch bridge with a main span of 192 m and large dip angle main-vice arches. The main arch is inclined outward at 73° and the vice arch is inclined inward at 45°. Based on this bridge project, this article describes the development and evolution process of the structural system and investigates the effect of the key parameters, such as the axis line and dip angle of the main arch. The conclusions can provide a reference for similar bridge designs.

摘要

The structure type of the No. 3 Ulanmulun River Bridge in Ordos City adopts a landscape arch bridge with a main span of 192 m and large dip angle main-vice arches. The main arch is inclined outward at 73° and the vice arch is inclined inward at 45°. Based on this bridge project, this article describes the development and evolution process of the structural system and investigates the effect of the key parameters, such as the axis line and dip angle of the main arch. The conclusions can provide a reference for similar bridge designs.
