Tilt displacement of caisson breakwater due to wave loading

Abstract: Tilting and overturning of caisson breakwaters due to wave loading is well documented. Although simplified methods of caisson analysis have been proposed, they are either fully elastic analyses that do not account for permanent displacement, or stability analyses that determine whether overturning will occur. In reality, a caisson can incur significant tilt without overturning: such a phenomenon cannot be replicated by either of the above analyses. This paper presents a simplified analysis that takes into acco… Show more

“…These two observations may seem less relevant due to the configurations of centrifuge tests, e.g. [7] (no rubble base and equivalent mechanical loading to simulate wave loading). The reason for the seaward tilt failure has been attributed to several mechanisms, including seabed scour or soil liquefaction underneath the breakwater heel (seaward side) and seawards directed impacts caused by excessive wave overtopping, which result in caisson tilting seawards.…”
