Review article

The paper presents the results of experimental studies of the effects of seasonal temperature changes on the stress-strain state of the "soil - shoring - expansion-type support" system. The research was implemented by the experimental technology department specialists of NIIOSP named after N. M. Gersevanov on a large-scale physical model of the pit. The research method and the equipment used are described. The dependences between changes of the force in the pit shoring at changes of temperature in the support system are determined. Experimental data are compared with the results of the numerical studies carried out previously.
