Effects of different empirical tunnel design approaches on rock mass behaviour during tunnel widening
Empirical based approaches play an important role in tunnel excavation and support system design. These approaches are considered to be very effective in optimising the process of tunnel excavation and particularly tunnel widening. Several reliable empirical approaches have been developed, however t...
