Application of Long-Span Through Steel Bridge in Foundation Pit Project at Crowded Intersection
Beret steel bridge is a kind of prefabricated bridge characterized with simple structure,fixed-pattern material,convenient transportation,convenience in assembly and disassembly,which has high applicability.Based on the construction of deep foundation pit at crowded road section in a city,a multi-Beret-girder through bridge with single-span at 33 m is proposed by investigation and comparative analysis in order to ensure the smooth traffic and convenience in construction at intersection.The structural design and load analysis of the steel bridge are combined with Midas,a finite element analysis software,to calculate the stress on main structure of the bridge.The results meet the requirements for traffic,bearing capacity and service,and serve as a reference for the application of Beret steel bridge in crowded intersections.
