|Abstract:||Severe tilting and overturning of caisson breakwaters due to wave loading is well documented. Current simplified methods of caisson analysis are either fully elastic analyses which do not account for permanent displacement or stability analyses that determine whether overturning will occur. In reality, caisson can incur significant tilt without overturning; such phenomenon cannot be replicated by either of the above analyses. This paper presents a simplified analysis which takes into account the elastic caisson response as well as the permanent tilt. Elastic response was simulated using a lump-mass-spring model. Permanent caisson tilt was analyzed based on the assumption of the caisson tilting over a circular slip surface beneath its base. Comparison with centrifuge model data shows that the dynamic slip circle is able to capture the progressive build-up of tilt reasonably well. Finally, a parametric study was presented which shows that the computed permanent caisson tilt can be reasonably well-correlated to a function of four dimensionless groups of caisson parameters. © 2010 by The International Society of Offshore and Polar Engineers (ISOPE).|
