NUMERICAL ANALYSIS OF THE ACCOUNT OF THE STAGES IN THE CALCULATION OF THE SHELL TOGETHER WITH THE SOIL MASSIF

Abstract

The distinctive paper discus ses the stress-strain state of a cylindrical shell with and without taking into account changes in the design model in time. The volumetric design model of the cylindrical shell and the soil massif is made. The calculation consists of several stages from the beginning of the tunnel shell construction to the end of the work. The authors analyzed the results and made appropriate recommendations.
