Features of the Nonlinear Calculation of the Stress-Strain State of the" Rock Massif–Excavation Support" System Taking into Account Destruction

摘要: The algorithm for estimating the reliability of the results of the calculation of the stress-strain state of the «rocN massif–excavation support» system, taNing into account the non-linear relationship between stresses and strains, as well as the destruction of the rocN, is presented. In the course of a numerical experiment, it was shown that to determine the reliability of the calculation results, it is enough to find the relative error between the maximum efforts in the lining and then the extremum (more precisely, the maximum) of the" relative error-depth of the excavation center".
