Hydrogeological monitoring on the landslide slope site in Sochi

Article preview

To form an estimate of stress state of rock mass of a sliding-down slope, in the town of Sochi 10 observation stations – bore holes were built-up at the depth of 50-150 m with the arranged sensing elements for hydrostatic pressure measurements. According to the results of observations which were carried out for two years, the regularities of groundwater flow were established, and also the hydrogeological structure of the sliding-down slope was revised. The sensor readings indicated the slight changes in stress state of the low-permeable paleogenic rock and overlaying sedimentaries. The periodical movements of overlaying sedimentaries of clay composition are attributed to the seasonal variations of their physical and mechanical properties.

Monitoring of hydrogeomechanical processes in the emergency section of the St. Petersburg subway

Article preview

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.
