砂土地震液化预测的 Bayes判别模型及其应用
Bayes discriminant analysis model for seismic sand liquefaction
摘要
Abstract
Based on the principle of Bayes discriminant analysis and the factors influencing the sand liquefac-tion,the model was applied to the prediction of sand liquefaction with eight factors listed as following:seismic intensity,epicenteral distance,groundwater level,sand depth,blow number of standard penetration test,mean granular diameter,coefficient of nonuniformity,ratio of shearing stress to effective overburden stress.With 2 1 groups of typical sandy soil seismic liquefaction data during Tangshan earthquake as samples,Bayes discrimi-nant analysis model of predicting earthquake liquefaction of sandy soil in Tangshan area is established.Then the model is applied to predict the sand liquefaction through other 9 samples.The results show that the prediction Model of Bayes discriminant analysis has excellent performances with high prediction accuracy.It is an efficient method for the prediction of sand liquefaction and could be applied to practical engineering.关键词
