Two models for sand liquefaction prediction are established according to the nonlinear classification of least square support vector machine(LSSVM). The prediction results from LSSVM are in keeing with the actual situation in field. It shows that the models for sand liquefaction prediction based on the LSSVM is feasible,and has high accuracy .
