Abstract
the design method of bearing capacity of rubble foundations for breakwaters was constructed assuming of the circular slip surface in rubble foundations. In our recent experiments, however, local destruction in the surface part of rubble foundations instead of the circular slip surface in rubble foundations has been observed. We consider that this local destruction relates directly to the loss of bearing capacity of rubble foundations. First of all, in this research, we confirmed that the numerical simulation by the distinct element method excellently reproduced these experiments. Next, the numerical simulations by the distinct element method to other assumption sections were done. As a result, it was shown that this local destruction was universal.
