Comparative analysis of modelling methods of the tunnel construction harmful effect

The article presents a comparative analysis of the results of mathematical modeling of horizontal tunneling in the Plaxis 3D software package. Two main ways of modeling the tunnel lining were considered: models based on volumetric elements and using the Plate tool. An analysis was made of the distribution of displacements and deformations on the surface: subsidence, inclinations, curvature, horizontal deformations. Comparison of the maximum strain values showed an insignificant deviation (approximately 5%), which proved the applicability of the two models. For further work, a method using the Plate tool could be recommended as being more suitable in the case of complex models with a large number of intersections.
