Summary: | The paper discusses identification of numeric model parameters of tunnel lining in a soil
medium according to the discrete element method. An author’s program based on the discrete element
method was used. Laboratory tests were conducted to determine the computer model parameters
defining the lining and the soil medium. The numerical model was calibrated by comparing the lining
deformations occurring in the laboratory test and in the numeric simulation. Tunnel lining displacement
during laboratory tests was determined using digital photography.
