A numerical model based on the method of Discontinuous Deformation Analysis (DDA) is presented to simulate the stability of rubble-mound breakwaters. The breakwater is considered as a stack of rigid blocks moving against each other and subject to seismic loading. The contact and cohesion between blocks as well as the geometric shape of the blocks are included in this analysis. A numerical simulation, with an analytical study, has been made to estimate the optimum cohesion between blocks necessary to increase strength and stability of the dam.(C) 2012 Academie des sciences.
