000019899 520__ $$2eng$$aThe design of structural foundations for tsunamis is a complex process that must account for the effects of erosion and local scour. As unsteady and violent tsunami flow propagates over the ground, it causes transient loads and reduced soil strength. Foundation design provisions must consider the cumulative effects of hydraulic processes (e.g., shoreward overland and overtopping flows, flow concentration, and downwash); geotechnical processes associated with the flow (elevated pore pressures, uplift forces on soil grains, and loss of shear strength in submerged soils); and residual soil liquefaction from near-field earthquake events. The new ASCE 7 provisions for Tsunami Loads and Effects address foundation design criteria by combining current methods in geotechnical engineering and sediment transport with observations of scour and foundation failures from recent large magnitude tsunamis. The provisions specify not only the evaluation of potential scour from tsunamis but also the design of tsunami countermeasures to both structures and sites. Structural countermeasures such as tsunami barriers as well as foundation countermeasures (pavements, revetments, geotextiles and ground improvements) are considered.
