Methodology of Prediction Stress-strain State Deep Foundation Structures of Subway Station's Taking Into Account Stages of its Construction

Abstract

The paper presents a methodology for predicting the stress-strain state of deep foundation constructions of subway stations. The methodology is based on an open dynamic system «rock mass - construction technology - subway station». This system takes into consideration the structural features of the stations and stages of their construction, that influence on the course of geomechanical processes. The proposed approach provides a complete picture about the stress-strain state of subway stations structures and basin subsidence of surfaces (мульды оседания поверхности) and can be used to justify the rational space-planning, constructional and technological solutions. Using of the open dynamic system “rock mass - construction technology - subway station” allow entry structural and technological changes in the developed base model for its adjustment in the process of construction and exploitation of subway station, in an emergency or other newly emerged factors that allows to quickly solve problems.
