Návrh ražby železničního tunelu Milochov

Abstract

The subject of the diploma thesis is The Design of Milochov rail tunnel. The Milochov tunnel is characterized by complex geological and hydrogeological conditions at the place of construction and due to this conditions has been created a mathematical model of the performance and behavior of the primary lining. The proposed designs are carried out using the PLAXIS program. The project and technical documentation served as the basis for the designing of the model. The output of the thesis is a design of the technological process of tunnel excavation based on the carried geological survey. There have been modelled two technology breakout classes. The first class deals with difficult and more complex geological conditions using an inverted arch matter. The second option reflects the theory to have a flat bottom. Subsequently the variants of the original design of the technological class are modelled using the inverted arch.
