COMPUTER AIDED DESIGN OF TUNNEL SUPPORTING SYSTEM S

Abstract

Tunnels *play an important role in Civil Engineering, particularly in Water Resources Projects, In general, it is necessary to provide a supporting system for the longterm stability of the rock opening. The steel rib, shotcrete and rock bolt supports are generally provided in any tunnel, These tunnel supporting systems must be capable of holding up. large blocks of rock material whose support was removed during the excavation process. Based on many varying factors -afffecting the tunnel such as : Geology, Topography, Material used for support, shape of tunnels and others, the alternatives of either type of support system may be adopted,....
