A three-dimensional model for predicting the spatial distribution of permanent ground displacements induced by liquefaction is presented.It is based on the principle of minimum potential energy.In the model,the area is divided into 2D-finite elements and the energy for each element is formulated in terms of the unknown nodal displacements.Then,the total energy of the system is minimized,and using variational principle,the solution is obtained.Settlements were calculated assuming constant-volume condition.The model was applied to several case histories and the results were in good agreement with the measured data. ƒL[ƒ[ƒhi‰pjF Liquefaction,Permanent Displacement,Finite Element Method ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
