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 of the rock stability surrounding a tunnel.
