Geotechnical approaches to safe development of the underground space in St. Petersburg

Abstract

Geomechanical approaches to creating the concept of safe development of the underground space in metropolitan cities have been considered. The concept of choosing geomechanically safe parameters of structures and technologies of building underground structures is based on the principle of minimizing the harm to urban facilities located on the surface of the earth. A method of predicting subsidence of the earth's surface in building underground structures in dense urban areas has been developed. Principles of developing slightly settling building technology to be used in the underground structures in metropolitan cities have been discussed.
