At present, the construction of pile foundation, prefabrication and processing preparation of steel structure, temporary wharf, steel trestle and sea area desilting are being carried out for the fourth cross sea bridge project of Macao Bay. The design work is carried out at the same time, and all the work is progressing steadily. The main bridge of Aoji No.4 bridge adopts the composite continuous beam structure of steel truss and steel box girder, and the approach bridge is multi span continuous steel box girder, and typhoon influence is frequent in the project area. In order to comprehensively evaluate the wind resistance performance and wind vibration characteristics of the bridge in the construction and operation stages, the wind engineering test and research center of Hunan University is entrusted to undertake the special research work of wind tunnel test of bridge solid model.<br>
