Abstract
The paper presents the results of field observations on formation of stressed state in shotcrete temporary tunnel support when constructing a traffic tunnel of NCRW near the slope. Numerical simulation of stressed deformed state of the «support – block» system has been accomplished for the considered engineering geological conditions. The results obtained point to a possibility of developing the procedure of calculating supports based on results of field observations under comparable conditions in combination with SDS modeling applying finite-element method adapted for specific conditions.
