依托嘉绍大桥工程，基于三维势流理论，运用流体动力软件SESAM对钢套箱围堰在强涌潮条件下的垂荡及荷载Fz响应进行了计算和分析。在5年一遇涌潮下，对钢套箱下沉过程中的垂荡及荷载Fz进行短期预报，得出在下沉过程中的最大垂荡振幅和荷载Fz值，从而确定嘉绍大桥主墩围堰下沉限位装置安全。

Relying on Jiashao Bridge project, based on 3D potential flow theory, the heave response and load Fz response of the steel caisson cofferdam was calculated and analyzed with strong bore by hydrodynamic software SESAM. Besides, the short-term prediction of the heave and load Fz with steel caisson cofferdam sinking was introduced for five-year return period of strong bore. The maximum value of heave amplitude and load Fz in the course of sinkage was obtained,which ensured the security of the limit device for the main pier cofferdam sinking of Jiashao Bridge.
