Description
Summary:In the framework of an approach based on the mechanics of a transforming structure, a method is proposed for calculating the deformation processes of elastoplastic reinforced structures interacting with soils of complex physical nature. The technique is based on the use of the defining relations, connecting the increments of the true stresses and strains. As an illustration of the performance of the proposed methodology, some results of the calculation of the stress-strain state of the walls of a metro tunnel station at different stages of its construction are given.
