Technicko–technologické zhodnocení způsobu sanace havárie tunelu Jablunkov

Abstract

The thesis deals with the technical-technological evaluation of the reconstrucion of the Jablunkov tunnel after colapse. It was required to ensure the stability of the geological environment with the result of reducing the negative impact deformation to the adjacent tunnel, and also to minimize the inflows and circulation of water for the next excavation. Part of the thesis is survey of the history of the tunnels, the redevelopment project, short descriptions and causes of incidents, an overview of the proposed gravity grounting and its evaluation. Grounting went though as expected and the results were clearly demonstrated during the actual recovery collapse and ordered measurements.
