Abstract

The paper deals with the analysis of the overall stability of caisson breakwaters exposed to impulsive wave loadings, in particular regarding sliding failure and failure in the subsoil. A comparison is made between prediction of sliding distances by a simple onedimensional (1-D) dynamic analysis and a dynamic two-dimensional finite-element analysis based on the ABAQUS code. Only the last method includes the deformation characteristics of the rubble foundation and sand subsoil. It is shown that the simple 1-D analysis somewhat underestimates the horizontal sliding distance of the caisson. Stability calculations based on equivalent static loads are discussed as well and it is concluded that foundation slip failure cannot be realistically analysed by such a method in the case of impulsive loadings.
