Abstract

The paper presents a prediction of liquefaction induced deformation of La Palma dam due to the 1985 Chilean earthquake using a simplified pseudo-dynamic procedure. The procedure is essentially an extension of Newmark's method from a rigid-plastic single degree of freedom to a flexible multi degree of freedom system. It takes into account both the effects of the inertia forces from the earthquake and the softening of the liquefied soil. The results show that the predicted displacements are in general agreement with field observations both in terms of magnitude and pattern of deformations.
