Sažetak
The formation of a deep slide induced by the excavation of a highway tunnel in a slope is described and analyzed. The slope is composed of Jurassic carbonate rocks above a subvertical fault, and of Palaeozoic clastic Rocks beneath the fault. The analyses of surveying data on the tunnel construction site and of geotechnical test results showed that a progressive slope failure was initiated. Regions of plastification and disturbance of the rock mass around the tunnel were determined by numerical modelling of the tunnel excavation using the computer program FLAC. Three-dimensional limit equilibrium stability analysis, taking into account the decrease of shear strength due to disturbance, gave the contours of a possible sliding body. Based on these analyses it was concluded that any continuation of excavation works in the slope might induce a general slope failure.
