..., normal stress and dilation behaviour with shear displacements are compared with the laboratory results. It is observed that UDEC can predict the peak shear stress of unfilled joints under CNS, however, it overestimates the joint dilation as well as the normal stress. The maximum peak shear stress in UDEC...

... that the progressive failure of the rock mass around a tunnel at depth. And the analytic formulas arc given to evaluate the effects of the softening and dilation of the rock mass on the stability of underground tunnel. Some suggestions are also given to improve the support of underground tunnel at great depth. I...
