摘　　要：针对目前围岩稳定性分类方法存在的不足 ,给出一新的分类法。首先利用基于MATLAB6.1编程的 6种改进的 BP算法分别对围岩稳定性进行分类 ,在此基础上选出一种最佳方法 ,然后利用该方法进行训练和检验 。In the light of insufficient classification methods of wall rock stability,a new classification method was given.First,the six improved BP algorithms based on MATLAB6.1 programming method were used to classify the wall rock stability respectiely and on this base an optimum method was selected.Then,the method was used to carry out training and checking.The practice showed that the method had better practicol effect.
