In this paper, a brief introduction of the new progresses in the field of tunnel mechanics is presented in combination with part of the results of our recent research works. The main points are:1. Nonlinear feed—back analysis of the parameters of rock mass and rock properties of surrounding rocks around the tunnel opening;2. Static interaction between viscous elasto—plastic geo—media with the tunnel lining structures;3. Calculations of viscous elasto—plastic mechanics of tunnel openings considering the time—space effect of tunnel working face;4. Problems on Construction Mechanics relating to underground works as excavating by parts of tunnel openings with large cross—sections as well as successive excavation by order of opening groups etc;5. Expert—intelligence system for optimization designing of tunnel sup port;6. Monitoring, feed—back and predictions in tunnel construction;7. Problems of tunnel dynanics.
