| Abstract: | In research on the stability of rock mass surrounding a tunnel,there are two major difficulties: determining the failure mode and confirming the failure criterion.On the basis of various methods for the stability analysis prevalent at home and abroad,this paper describes calculate models and their quantitative failure criterions under different deformation mechanisms,analyses the development and limitation of the different methods,and puts forward operational criterions for quick and appropriate evaluation ... |
