Abstract
The hydrodynamic regime is monitored by 90 hydrostatic pressure sensors placed at different depths in the heterogeneous thickness of quaternary deposits. Total, neutral and effective stresses along the route of projected tunnels were determined. Seasonal changes of hydrostatic pressures in the thickness and their connection with atmospheric pressure are estimated. The reaction of water-saturated massif to tunneling with bottom-hole hydroloading has been fixed.
