Alternativní možnosti doplňujících sanačních opatření tunelu Homole

Abstract

This diploma thesis deals with alternative options for additional rehabilitation of the Homole tunnel on the highway D35, in the area Ostrov – Vysoké Mýto. The theoretical part is processed with the documents for the highway D35, tunnel Homole and other research processing of additional rehabilitation for tunnelling. The design and calculation are carried out in the calculation program Plaxis 2D and the drawing program AutoCAD. There are created four variants of calculations model. The focus of the additional rehabilitation in the model is on the right tunnel because of low overlay and higher total displacement (about u = 0,024 m). There are additional rehabilitations in the form of artificial ground freezing and two types of jet grouting are proposed in the calculation program Plaxis 2D. The results of these analyses are evaluated at the end of the thesis.
