Unit energy level associated with pore pressure development during liquefaction J.L. Figueroa Department of Civil Engineering, Case Western Reserve University, Cleveland, OH 44^06, USA ABSTRACT The phenomenon of liquefaction of saturated sands has been understood in a qualitative way for many years. If saturated sand is subjected to dynamic loading, it will tend to decrease in volume. If drainage is prevented because of added dynamic loading the tendency to decrease in volume results in an increase in pore water pressure. When the increase in pore water pressure equals the overburden pressure, the sand loses its shearing resistance, and then liquefies. Several investigators have suggested that a given level of energy is associated with the permanent rearrangement of sand particles, and under a certain set of conditions it is assumed to be a constant quantity. This paper describes the development of pore pressure during liquefaction tests as a function of the accum
