Scheme Conceptualization and Comparison Study of Main Bridge of Linyi Yellow River Bridge
In order to obtain a reasonable bridge-type plan for the main bridge of Linyi Yellow River Bridge to guide the design of the construction drawing,starting with the bridge construction conditions,this paper conceptualizes the bridge foundation forms,construction method,bridge spans,and bridge types and conducts the same depth design,comparison,and study of four main bridge type schemes of PC continuous rigid bridge,plate-truss composite girder bridge,steel box composite girder bridge,and I-beam composite cable-stayed bridge.The results show that the PC continuous rigid bridge's cost occupies 69％of the total,and the utilization rate of the pile foundation is low.The cost of the I-beam composite cable-stayed bridge exceeds the estimate of the engineering feasibility study,and the cable bend tower and ties greatly disturb the habitat and migration of birds in the conservation area.The utilization rate of the steel box composite girder bridge is better than that of the plate-truss composite girder bridge with the same construction scale.So it is recommended that the main bridge of Linyi Yellow River Bridge adopt the continuous steel box composite girder bridge with a span of 128 m.
