| Abstract: | The complexity of rock masses and soils leads to errors in the numerical analytical results on excavation deformation. The authors identify factors that cause such errors, discuss how those factors affect simulation results, and how the effects of such errors should be reduced to assure the accuracy of numerical simulations. |
