Geogrid Reinforced Subbase under the Impact of Mining Subsidence

[摘要] The subject of the article is a numerical simulation of the dynamic response of a concrete slab on an elastic subsoil on the effect of moving vehicle. The vehicle model and the slab model on Winkler and Pasternak subsoil are described. The method of calculating the subsoil constants for both models is presented. The numerical solution is carried out in MATLAB using the ode45 procedure. Considerations are made about the suitability of the used models and possible corrections of results for the Pasternak's model are presented. The results of the solution are presented in numerical and graphical form.
