Abstract
Earthquake induced liquefaction of sediment stored behind dams can give rise to high uplift pressures which could endanger their safety. The uplift pressures depend upon the permeability and compressibility of both the sediment and the foundation and are controlled by Biot's equation. Uplift pressures are computed for a single dam and foundation with a range of properties. The results show that for the conditions analyzed, the uplift pressures are largely controlled by the foundation permeability with the largest uplift pressures occurring for the highest foundation permeability. The possibility of liquefied sediment flowing into fissures in the foundation rock is also considered and can result in much higher predicted uplift forces. This condition is only likely to occur for a foundation rock of high permeability.
