| Abstract: |
| Based on the survey to displacement of wall rocks of an opening,the identifiability and stability of identifying the mechanics parameters of a rock mass and the parameters of original stress condition with artificial neural network were investigated in this paper The relationship between parameter number to be identified and item of displacement survey was found out Suggestions for selecting survey items of opening displacement was put forward |
