Abstract: |
The density of the railway network in the Czech Republic is 122 km/1, 000 km², among the highest in Europe. Despite the fact that the surface relief cannot be compared to that of Alpine countries, the development of tunnels has been inherently associated with the development of railways in our country. The first railway tunnels were driven as early as 1845 and the number grew to 109 by 1900. At the end of World War II in 1945, 100 years after the construction of the first tunnel, there were 143 railway tunnels in our republic. After the assumption of power by the communist regime, the development of tunnels stagnated and the Iron Curtain prevented even the opportunity for contacts with engineers in countries with developed tunnel construction and engineering. Modern tunnelling methods were only employed after the Velvet Revolution in 1989, when the intention to incorporate the Czech Republic into the European infrastructure initiated the development of railway transit corridors. The corridors are selected railway routes where higher speeds are possible than on our current railway network, the majority of which runs on tracks from the 19th century and first half of the 20th century, and entailed modification of horizontal and vertical alignments. |
