Abstract :
Based on projection pursuit regression method, this paper had a analysis on liquefaction grade of sand soil. Taking epicenter distance, effective pressure overlaying, standard penetration test, water table, circular shearing strength ratio as independent variables, and liquefaction grade of sand soil as dependent variable, the confirmation model of liquefaction grade of sand soil was obtained. It was found that, the confirmation value of liquefaction grade of sand soil was consistent with actual measurement value of liquefaction grade of sand soil for 32 groups of independent variables training model and 4 groups of independent variables validating model. The following conclusion can be drawn that, the prediction model is accurate and credible, and the projection pursuit regression method is a eximious method, and it is worthy to spread its application in the prediction of liquefaction grade of sand soil.
