Investigation of tunnel seismic resistance according to various loading schemes of the theory of seismic resistance of underground structures

Abstract

The article considers the study of the seismic resistance of tunnels according to various loading scheme
of the theory of seismic resistance of underground structures. The problems of seismic resistance of
underground structures are presented theoretically and experimentally. The problems of assessing the
seismic impact on underground structures, in particular tunnels, are among the most difficult problems.
Currently, several theories have been developed based on calculation schemes, which can assess the
stress-strain state of underground structures, in particular shallow and deep tunnels. To carry out the
calculation as a real lining of the subway tunnel. The tunnel is being built by an open method of work in
dry loess soils. The geometric and physical characteristics of the structure and the soil are also given
here. The mathematical apparatus and software package developed by the author currently allows for this
kind of research.
