Yufeng Xu, Yue Li


The Xinguang Bridge, crossing the shipping channel of the Pearl River in the city of Guangzhou, is a three-span continuous half-through rigid frame steel truss arch bridge with two RC V-shaped triangular rigid frames. The paper first gives a brief introduction on the important engineering aspects. Then the characteristics of this bridge such as the supporting system, structure of the deck system, horizontal tie, arch rib, vertical suspender, V-shaped triangular rigid frame, and foundation are investigated herein are given detailed demonstration. The conclusions and future prospects are finally presented.
