Modeling of the Interaction of a Large-Sized Shell with a Ground Environment During Immersion

Abstract

Large-sized reinforced concrete shells are rationally used in the underground construction of transport and engineering infrastructure facilities. For the defect-free construction of an underground structure, it is necessary to jointly solve complex design and geotechnical tasks. The interaction between the solid structure and the ground environment, as well as the heterogeneity of the medium itself, give rise to the need to control the stress-strain state of the "large-sized body - heterogeneous medium" system. Modeling the interaction of the shell with the ground environment and forecasting stress and strain management provide conditions for a defect-free life cycle of the structure during its construction and operation in difficult soil and man-made conditions. The article offers the basics of the concept of assessing the interaction of large-sized submersible structures in soils with different stability, taking into account the unsteadiness of the immersion mode for engineering and transport infrastructure facilities.
