The paper presents a numerical analysis of the effect of taking into account the stages of construction on the stress-strain state of a tee joint interacting with a soil array. The study of such systems is in demand by modern practice. For example, during the construction of the subway, there is always a need for tunnel connection structures that ensure the functioning of the main tunnels and stations. Calculated cases with a different number of stages of construction (0, 1, 2, 4, 8 and 40) tee connection have been compiled and the results were obtained. It is established that the correct accounting of successive stages of construction plays a key role in correct determining the stress-strain state of the shell-ground systems.
