Geotechnical Protection of Engineering Infrastructure Objects in Large Cities Under Intense Anthropogenic Impact and Long Term Operation

This article describes more than 30-year experience of scientific and technical support, design, construction and reconstruction of water supply and sewage facilities in St. Petersburg, Sochi, etc. Describes the specific defects of long-term operation of large-size pumping stations and deep-laid tunnels that cause risks and dangers of their use. It gives the results of geotechnical and design calculations, modeling of underground and tunnel constructions taking into account risk factors determined by defects that occur during construction and operation, and also taking into account external influences, including dynamic ones. The report gives a comparative analysis of calculated and industrial experiments, provides activity and implementation experience of geotechnical support of long-term operation of engineering infrastructure.
