【 摘 要 】

The South Anchorage caisson of Oujiang Beikou Bridge in Wenzhou adopts the scheme of "four successive heights and four subsidences", which will be attacked by typhoon during the period of caisson heightening. In order to ensure the caisson passes through typhoon season smoothly, the anti-wind stability of the caisson secondary connecting section under different wind speed and different action angle is checked. The results show that the maximum displacement of the structure increases sharply with the increase of wind speed, and the effect of load direction on the maximum displacement of the structure is less than the influence of wind speed. The relevant conclusions can provide guidance for the safe passage of the high section of Caisson in typhoon season.
