Ayaş Tunnel
The Ayaş Tunnel () is a railway tunnel under construction near Ayaş town of Ankara Province in Central Anatolia, Turkey. It was initially projected to shorten the railway line connecting Ankara with Istanbul. Background The construction of Ayaş Tunnel was planned in 1943 as part of a higher-speed rail service project. The -long tunnel would enable the railway ministry to shorten the distance of between Istanbul and Ankara by about to . The travel time would reduce from seven-and-a-half hours to two-and-a-half hours. After 33 years of suspension, the project came into force in 1976 when groundbreaking took place in the presence of Prime Minister Süleyman Demirel on the western entrance at the Ayaş side of the mountains. The next year in 1977, Deputy Prime Minister Necmettin Erbakan initiated the digging work at the tunnel's opposite entrance in the east near Erkeksu village. At that time, it was announced that the construction of the -long tunnel would be completed in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Austrian Tunnelling Method
The new Austrian tunneling method (NATM), also known as the sequential excavation method (SEM) or sprayed concrete lining method (SCL), is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses. This technique first gained attention in the 1960s based on the work of Ladislaus von Rabcewicz, Leopold Müller, and Franz Pacher between 1957 and 1965 in Austria. The name NATM was intended to distinguish it from earlier methods, with its economic advantage of employing inherent geological strength available in the surrounding rock mass to stabilize the tunnel wherever possible rather than reinforcing the entire tunnel. NATM/SEM is generally thought to have helped revolutionise the modern tunneling industry. Many modern tunnels have used this excavation technique. The Sequential Excavation Method is very cost effective, even in karst conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cut-and-cover
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 ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Trona
Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na2CO3·NaHCO3·2H2O) is a non- marine evaporite mineral. It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production. Turkey is also a major producer. Etymology The word entered English by way of either Swedish () or Spanish (), with both possible sources having the same meaning as in English: the mineral natron from North Africa. Both the Spanish and Swedish terms derive from the Arabic ''trōn'', which in turn derives from Arabic ''natron'' and Hebrew (''natruna''), which comes from ancient Greek (''nitron''), derived ultimately from ancient Egyptian ''ntry'' (or ''nitry'’). Natural deposits Trona is found at Owens Lake and Searles Lake, California; the Green River Formation of Wyoming and Utah; the Makgadikgadi Pans in Botswana and in the Nile Valley ...
