The contact interaction of the lining of city shallow tunnels
with rock massive when calculating the action of the surface load

The article deals with the issues of calculating the surface load on the lining of urban underground structures. It presents a design diagram of the linings of shallow tunnels as well as the solutions of elastic-dynamics contact problems for loads of two categories: applied before and after tunnelling. The numerical calculations made it possible to determine the regularities causing the stress-strained state of the lining.
Key words: shallow tunnel, surface loading, lining calculation, method.
