- Abstract
There is no simple analytic solution about tunnels with non-symmetry central section like horseshoe-shaped sections and for situation survey of Tangential Stress on Tunnel Portal compound. The approximate solutions are able to catch the stresses by confined component. In these sections, created Boundary Stresses on ceiling or tunnel partitions depend on tunnel section-shape and horizontal and vertical ratio of site. For utilizing created stress concept besides underground holes, it is necessary to have criteria or set of rules, to be able to predict rock mass response to sets of created stress (in this case Hook destruction criterion was used). The aim of this paper is to show created Boundary stresses on ceiling or tunnel partitions are depends on tunnel section- shape and horizontal, vertical ratio of site. It can conclude from satisfactory results using Hook destruction criterion is effective to predict rock mass response to sets of created stress.
