Abstract
This paper discusses the geobiological and hydrogeochemical processes in St.-Petersburg underground space and their role in corrosion of escalator constructional materials. The special attention were attracted to the ecological conditions which are connected with organic, inorganic contaminants and microbiota transporting to soils and groundwater from leaking sewer system and also from zones of long existing cemeteries. A detailed study and numerical analyses of escalator tunnel constructional materials were carried out to reveal biological defeat and destruction of concrete and grey iron as a result of microbiota destructive activity.
