Prediction of Lateral Spreading Displacement on Gently Sloping Liquefiable Ground
A fully coupled numerical analysis using Biot’s theory with u-p formulation considering variable permeability during liquefaction is used in this study to simulate liquefaction induced lateral spreading phenomenon. A centrifuge test performed on liquefiable soil at Rensselaer Polytechnic Institute is simulated using the developed model. The numerical results are in good agreement with experimental observations. A number of numerical simulations under different geometric, site-specific, and ground acceleration parameters have been carried out in the course of this study. Based on the statistical analysis conducted on the results of 31 different models, a new relation is proposed for predicting the liquefaction-induced maximum lateral displacement for gently sloping grounds. The proposed relation can predict the maximum ground lateral displacement obtained by the rigorous finite element analysis with less than 10% error. The predicted lateral displacements are in a good consistency with the ground movement observations in 16 different centrifuge tests as well as more than 250 field observations. The proposed relation in this study shows a better match compared to other well-known relations.
