Study on Low Frequency Horizontal Motions of a Large Caisson in Severe Current

Abstract:

Caisson is a commonly used foundation in modern bridge engineering. When the caisson is sinking towards the seabed, it will suffer from the coupled effects of wind, current and its mooring system, under which an intense horizontal oscillation might occur. The mechanism of this kind of oscillation can be concluded as Vortex Induced Motions (VIM) of a large floating object in resilience mooring system. In this paper, through numerical simulation of the viscous flow field around a certain caisson, the mechanism of vortex shedding under different current velocity is discussed.
