Abstract
A new empirical method for evaluating liquefaction-induced vertical displacements is presented, which is based on results obtained from a Multi-Linear Regression (MLR) analysis of field performance records. Previously published techniques for predicting earthquake-induced settlements are based primarily on results derived through laboratory cyclic triaxial testing. Consequently, settlements obtained by such methods account only for the effect of the volumetric strains. In the field, observed vertical displacements are a function not only of the volumetric strains but also the vertical component induced by lateral spreading and the effects of sand boils. In the present study, a MLR model based on field data is developed for predicting liquefaction-induced vertical displacements. A database consisting of 50 measurements of vertical displacement forms the basis for the MLR model and analysis.
