DYNAMIC FLUIDIZATION OF SOILS

This examination of the behavior of soils in an earthquake, assumes that imposed accelerations at some critical level will change the state of the soil as a whole. It is shown the the free-field limit analysis of a homogeneous layer of dry soil excited by uniform horizontal and vertical acceleration components leads to two simple equations describing the progressive yield or fluidization of the layer due to the intertial body forces. All intermediate stages, both active and passive, from static conditions to the final state of general fluidization are shown as an interrelationship between the severity of the acceleration ratio, the strength parameter, and the coefficient of lateral pressure.
