摘要

Taken the 90+3×160+90m prestressed concrete continuous rigid frame bridge as the research object, the wind pressure distribution in different states of rigid bridge cantilever construction, characteristics of aerostatic coefficient windward and leeward side of the bridge and the wind-induced vibration response under different wind direction of the twin deck bridge were studied by pressure-measurement, sectional and aeroelastic model wind tunnel test. Then combined with test results and numerical calculations, the various stages of the pressure distribution and wind loads were analyzed. At last, the wind load internal forces of the longest double-cantilever construction state were gotten. This data will provide a strong reference for the continuous rigid frame bridge design.
