Description
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. Keywords: civil engineering, discrete element method, cylindrical tunnel lining
