Experience of studying natural and technogenic processes in the underground space of St. Petersburg (on the example of the Obukhovo-Rybatskoye tunnels)
- Postgraduate student G.V. Plekhanov Saint Petersburg Mining Institute
Abstract
It is marked out the levels of development in Saint-Petersburg underground space, where separately should be taken in consideration the influence of structural-tectonic, engineering geological, hydrogeological, geoecological factors on an occasion for the display of exogenous processes and as a result of buildings stability. Main natural and technological factors, which play negative part in development of prolonged and uneven deformations of the tunnels «Obuhovo – Ribackoe» in Saint-Petersburg subway are considered in the article. It is emphasized that the character and intensity of tunnel’s throw depends on conditions, physico- mechanical rocks and soils properties, hydrodynamical and hydrochemical groundwater conditions, as well as gas-dynamic phenomenon. It is shown the profound effect of biocorrosion processes in lining material destruction.
