Abstract
The problem of surface subsidence under intensive downward influence of artesian waters is considered. Changes in the Lower Kotlin aquifer affecting surface and underground structures in St. Petersburg are characterized. Examples of destruction of structural materials during the construction of transportation tunnels are shown. Recommendations on prevention of corrosiveness of structural materials are given.
