Abstract

The situation when two geotechnical structures, the approach cutting and tunnel, are situated in the same area of action, i.e. in the approach cutting zone of the tunnel, is described in the paper. The influence of tunnelling work on the stability of the approach cutting is studied. The strain analysis based on the three-dimensional numerical model, which simulates the actual approach cutting and tunnelling work, is presented. The technogical solution for reducing the tunnelling work impact on slope stability in the approach cutting zone is also proposed.
