STRESS AND STRAIN ANALYSIS DURING THE SLEME TUNNEL EXCAVATION
(Reviewed by the editorial board member B. Maslov) A stress and strain analysis by Finite Element Method (FEM) has been carried out during the portal section excavation for the SlemeTunnel right tube.
A comparison has been made of 2D and 3D model results with on-site measurement results for tunnel convergence and ground sur-face settlement. Multistage excavations with pipe roof support of the working face were modelled. The calculation model has shown that safe and cost-efficient excavation technology had been applied in the case under con-
sideration.
