Comparison of Construction Schemes for Constructing Concrete-Filled Steel Tube Tied Arch Bridge in Shallow Water Channel

Abstract

To support this paper, the under-construction Wang’anshi Fuhe Bridge (main span 168 m), a mid-through tied arch bridge with concrete-filled steel tube (CFST), is taken as the research object, to discuss the advantages and disadvantages of the two construction procedures of the first-arch-then-girder, and the first-girder-then-arch. In account of construction difficulty, environmental influence, construction period and economy, the advantages and disadvantages of each construction method is revealed from construction methods including tower crane, gantry crane, and island building, which puts forward the optimal construction method and main control points of CFST tied arch bridge in shallow water channel.
