Overall Design of a River-Crossing Bridge & Connection Project
Taking the overall scheme of a river-crossing bridge in Guigang,Guangxi Zhuang Autonomous Region as an example,this paper determines the route and profile design scheme of the river-crossing bridge and the connecting line based on the road function positioning,combined with the planning conditions,the crossing mode of the flood dike,the navigation clearance and the river crossing mode of slow traffic.It focuses on the structural selection of the main bridge of the river crossing bridge,and puts forward the bridge type schemes of 335 m main span central cable plane cable-stayed bridge,suspension bridge,double cable plane cable-stayed bridge,and steel box basket arch bridge.Combined with one bridge & one landscape,the central cable plane cable-stayed bridge is determined as the recommended bridge type of the main bridge after comprehensive comparison,which can provide reference for similar projects.
