DAI Youcai1,ZHONG Cheng2(1.Hunan Road & Bridge Construction Group Corp,Changsha,Hunan 410004,China;2.Hunan Changxiang Expressway Constraction Development Company Ltd.,Changsha,Hunan 410219,China)  
Based on the Bayes discriminant analysis theory and method,and considered five indexes reflecting the shrink and expansion of expansive soil: content of clay grain,content of powder grain,liquid limit,solid limit and plasticity index,a Bayes classification model of expansive soil was established in this paper.An example was given to show the procedure of the model,and the reasonablencess and effectiveness of the model were proved by the example.
