Abstract The paper presents a comparison of different approaches to the problem of considering the phenomena of shrinkage and creep of concrete during underground construction in a rock salt mass. The comparison is based on the results of numerical modelling of the stress-strain state of the mine shaft lining. As a result of modelling studies, a significant influence of the method of considering the shrinkage and creep of concrete on the results of calculations has been established, which is especially important given the trends in changing the compositions of modern concrete and the characteristic differences in the formulations of concrete used in underground construction. Based on the results obtained, it is recommended to consider established phenomena with the use of creep functions directly taking into account the features of the formulation and technology.
