Abstract
Methodology for the application of one- and two-dimensional elements in the mathematical modeling of the subway tunnel lining
Incoming article date: 08.06.2022In connection with the development of computational complexes of the finite element method, sometimes there is a problem of choosing methods and techniques for numerical experiments with the lining of interlinear subway tunnels. The aim of this article is to consider the possibility of using one-dimensional and two-dimensional elements in modeling the lining of an underpass tunnel and the necessity of using contact elements in modeling the lining. In order to fulfill this task, two computational schemes with the lining modeled by one-dimensional elements and by two-dimensional elements have been created using the example of the existing Moscow Metro tunnel.
