Study results of a stress-strain state of a pylon station construction from monolithic reinforced concrete in the engineering and geological conditions of St. Petersburg

In recent years, structures made from monolithic reinforced concrete have been increasingly developed in the field of underground construction. This has possible by development modern tunneling technologies such as NATM and ADECO&RS, which proven themselves abroad. Being low-sedimentation methods construction, they found wide application not only mountain transport but also construction an urban environment, where precipitation negative impact on surrounding infrastructure a decisive role choice one or another technology. Foreign experience same physical mechanical characteristics soils gives reason to assert possibility using new our country. However, this task requires comprehensive approach its solution. article presents experimental theoretical substantiation pylon station lining engineering geological conditions St. Petersburg example planned Metro “Chernigovskaya” “Krasnoselsko-Kalininskaya” line being built “Obvodniy Kanal-2” “Yugo-Zapadnaya” station.
