GEOMECHANICAL ASSESSMENT OF THE INFLUENCE STRENGTHENING ROCKS ZONE ON UNDERWATER TUNNEL LININGS BEARING CAPACITY

The approach for assessing the stress-strain state and bearing capacity of monolithic linings of underwater tunnels constructed with the use of reinforcing grouting of the surrounding soil massif is proposed. The method makes it possible to determine the necessary parameters of underground structures based on the analysis of the boundaries of their areas of application. In order to implement the developed theoretical provisions, an original analytical solution of the corresponding plane problem of elasticity theory was applied, implemented in the form of a computer program.
