Abstract

Based on the Shenzhen Bay Bridge which is located at the center of park cultural landscape, so it has important requirements of improving environments , protecting the environment and beautifying the environment. the bridge is optimal designed to be a flying swallow type curve special-shaped composite arch bridge.The difficult question that on the condition of ocean foundation,the curve beam through tensing the tie bar can't eliminate the horizontal thrust was solved through the conjoined main and deputy arch are the same goals and supplement and complement to each other.Increasing ties between arch rib through the wind bracing and using corrugated steel-web and cantilever truss composite structure to form the longitudinal box girder ,which increase the bridge deck width and improve the stability of bridge structure.The plane curve girder is united with arch rib by single cable plane suspender to form a space curve,which solves the torsional problems of single cable plane curve beam.and avoids the staggered messy visual of double cable plane.Box-girder bridge with corrugated steel webs- truss composite compared to traditional pre-stressed concrete box girder, which can reduce the dead weight of beams and solves the problem that the traditional prestressed concrete box girder web plate is easy to crack,and so on. Flowing curve modelling adds to the beauty of the city of Shenzhen.In design, it takes into account the traffic function, and fully embodies the times tinge of modern bridges in the urban landscape,it provides a new ideas for large span curve special-shaped composite arch bridge.
