Mont D'Ambin Base Tunnel
The Mont d'Ambin Base Tunnel, also known as the Mont Cenis Base Tunnel, is the largest engineering work of the Lyon–Turin rail link project. Once completed, it will facilitate the principal high-speed rail link between Italy and France, conveying both high-speed passenger trains and rail freight between the two countries. At , that tunnel will be the longest rail tunnel in the world, ahead of the Gotthard Base Tunnel. It represents one third of the estimated overall cost of the project and is the only part of the line where work has started. Crossing the Alps between the Susa Valley in Piedmont and Maurienne in Savoie. It has an estimated cost of €8 billion. During September 2016, a key agreement towards the tunnel's construction was reached by France and Italy. Three years later, competitive tenders to perform packaged elements of the construction work were sought. As of late-2022, the expected completion date for the base tunnel was 2032.

Rail Electrification
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding "pickup shoe". ...

Drilling And Blasting
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite. Before the advent of tunnel boring machines (TBMs), drilling and b ...

Schist
Schist ( ) is a medium-grained metamorphic rock generally derived from fine-grained sedimentary rock, like shale. It shows pronounced ''schistosity'' (named for the rock). This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture (geology), texture reflects a high content of platy minerals, such as mica, talc, chlorite group, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building (orogeny) and usually reflects a medium Metamorphism#Metamorphic grades, grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yulhyeon Tunnel
The Yulhyeon Tunnel () is a railway tunnel in South Korea, which opened in 9 December 2016, and is currently the world's fourth longest railway tunnel at . The tunnel, which consists of a double-track tube, is part of the Suseo–Pyeongtaek high-speed railway and GTX-A that connects Suseo station in the southeastern part of Seoul with the Gyeongbu high-speed railway. The threading into the older high-speed line is in the south of the city of Pyeongtaek. The tunnel itself takes up about 82% of the total new line. The Yulhyeon Tunnel was built using the New Austrian tunnelling method (NATM) and is designed for a maximum speed of . The average cruising speed is about due to the intermediate stop at Dongtan Station in the southern part of the tunnel. Structural issues The major section of Yulhyeon Tunnel has been built over the seismic fault called Singal Fault, which triggered an inquest into its structural stability.

Brenner Base Tunnel
The Brenner Base Tunnel (; ) is a railway tunnel under construction through the base of the Eastern Alps beneath the Brenner Pass. Once completed, the Brenner Base Tunnel will rank as either the second or third longest railway tunnel in the world, depending on the definition employed. It will be surpassed in length only by the Gotthard Base Tunnel in Switzerland and, depending on the relative completion dates of these projects, the Mont d'Ambin Base Tunnel between France and Italy. When combined with the Inntal Tunnel, which forms part of the existing Innsbruck bypass, the Brenner Base Tunnel will reach a length of , making it the longest underground railway connection in the world. It will run from near Innsbruck, in Austria, to Franzensfeste/Fortezza, in Italy, replacing part of the current Brenner railway. The line is part of Line 1, the Berlin to Palermo route, of Trans-European Transport Networks (TEN-T) and funded by Austria and Italy with large contributions by the ...

Tunnel De Base Du Mont D'Ambin
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two Portal (architecture), portals common at each end, though there may be access and ventilation openings at various points along the length. A Pipeline transport, pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passa ...
