Construction Technology of Continuous Beam Arch Bridge Crossing Expressway with a Sharp Skew Angle
[Purposes]This paper aims to guide the construction of the same type of continuous beam arch bridge at a small angle across the expressway,and ensure the smooth progress of the entire project con-struction.[Methods]This article takes the Chuannan Intercity Railway as the main research object,fo-cusing on the construction of continuous beams,steel pipe arches,and roadbed cross-sections.[Find-ings]Based on the actual construction situation,the cantilever pouring method bracket structure is de-signed,and the optimization design content is analyzed to obtain the most scientific design method.[Con-clusions]The practical results indicate that through scientific construction,the construction plan for small angle diagonal spans of continuous beam arch bridges has good feasibility,which has important ref-erence value for the construction of large-span bridge projects such as highways,and also provides refer-ence for research in related fields.
