abstractsThe paper deals with engineering analysis of breakwater behaviour due to earthquake- induced subsoil liquefaction. First, a simple model enabling analysis of pore-pressure generation in saturated granular soils, due to cyclic loading, is outlined. It is also shown how this model can be applied to the analysis of seabed behaviour during earthquakes. Then, a simple model of breakwater resting on saturated subsoil in which the phenomena of pore-pressure generation and liquefaction take place is described. This model enables estimation of changes of seabed effective reaction due to pore-pressure generation, as well as subsequent sinking of the breakwater due to subsoil liquefaction. Numerical examples illustrate theoretical considerations and show links between breakwater behaviour and earthquake characteristics.
