主　　题：underground opening over-excavation Bayes discriminant analysis forecast 

摘      要：A method to forecast the over-excavation of underground opening by using the Bayes discriminant analysis(BDA)theory was *** Bayes discriminant analysis theory was *** on an engineering example,the factors influencing the over-excavation of underground opening were taken into account to build a forecast BDA model,and the prior information about over-excavation of underground opening was also taken into *** parameters influencing the over-excavation of opening,including 2 groups of joints,1 group of layer surface,extension and space between structure faces were selected as geometric *** data in an underground opening were used as the training *** cross-validation method was introduced to verify the stability of BDA model and the ratio of mistake-discrimination was equal to zero after the BDA model was *** in an underground engineering were used to test the discriminant ability of BDA *** results show that five forecast results are identical with the actual situation and BDA can be used in practical engineering.
