摘要：

The paper presents an evaluation of 3D numerical modeling of the first road tunnel built mining method in Poland, on the Polish-Slovakian border. The Laliki tunnel presents a unique ease for an assessment of 3D numerical modeling as a tool for tunnel design due to detailed data being available from monitoring during construction. Geotechnical evaluation carried out for the project proved insufficient, which called for an urgent necessity to work out an additional reinforcement of preliminary lining, using forepoling as the arch support. Stability analyses of the tunnel with new lining were carried out on the basis of 3D numerical modeling of displacements and stresses around the tunnel.
