Sažetak
Foreseeing of the rock massif behaviour in tunnel breaking out is a complex engineering problem. In projecting it is important to evaluate the stability conditions in excavation and after the acceptance of suitable breaking out methods, the acceptance of supporting in order to stabilize the opening. The New Austriam Tunnel Method is the axcavation method adaptable to frequent changes of geological and geotechnical conditions at the working face. Beside the excavation of the whole profile, excavations in soft materials along the tunnel route condition, so-called profile development, i. e. the application of multi-phase excavation. This paper compares the conditions of stresses and strains for the whole profile excavation with condition of stresses and strains in multi-phase excavations according to the New Austrian Tunnel Method. Since the applied supporting system decisively influences, beside the way of excavation. The condition of stresses and strains near the tunnel opening, the comparison also refers to the whole profile excavation insured with primary support. For the analysis of stress condition in tunnel excavation the Boundary Method are used.
