The Deformation Control Analysis of the Joint Construction System of Urban Road Bridge- Subway Depot Cover Plate

Aiming at the demand of function compound of the subway depot cover plate, this paper puts forward the joint construction system of urban road bridge- subway depot cover plate combining with the specific project. In order to meet the requirements of structure design of that system, this paper conducted an equivalent conversion for city - A level load, etc. of the bridge design codes, then Midas Civil was used to build the overall bridge analysis model, Midas Gen was used to build the floor finite element model, YJK was used to build the structural engineering design model, then the results were compared and analyzed to prove the reasonableness of the conversion, the lane load and the truck load were respectively 27.9kN/m2 and 39.2kN/m2 after conversion, et, further we designed the structure according to the results of analysis, which can provide the reference for subsequent similar composite function structures.
