Hazardous processes may differ significantly at different intervals of an extended underground structure and at different times. This requires a dynamic approach to assessing, forecasting and reducing probability of emergency situations, as well as minimizing losses in different areas of the object. Therefore, it is reasonably to evaluate the influence of negative factors on extended underground structures from the standpoint of risk management. Geotechnical risks make the most significant contribution to the level of uncertainty in making design and constructive decisions due to their nonlinear variability both in terms of area and depth, and in time. For the purposes of geotechnical risk control in time can be successfully applied tools of digital geomechanics, mathematical modeling, deep learning methods based on neural networks, algorithms for evaluating the technical condition of underground structures based on BIM technology. The initial information is a field study of the stress-strain state of structures and enclosing environment as a part of the system of multi-disciplinary geotechnical monitoring which provides the development of possible accidents scenarios with the manifestation of each risk-criterion indicator hazardous for the tunnel.
