    Wybrane zagadnienia konstrukcyjno-technologiczne budowy pierwszego w Polsce tunelu tramwajowego
    (Wydawnictwa AGH, 2009) Ryż, Karol
    Structural and technological characteristic of the first tram tunnel in Poland (Cracow) is presented in the paper. The tram tunnel (1538 m length) together with stations belong to the first fast tram line in Cracow. Shallow tunnel has non uniform structure. Single chamber cross section was used at south-east part of tunnel, built with various methods of construction. Milan method was applied under Lubomirskiego Street. Vertical walls were made using secant piles (big diameters) and the ceiling is monolithic (reinforced concrete deck). Diaphragm walls were used at the end part of tunnel near Mogilskie traffic-circle. Part of the tunnel under main railway station as well as under Rakowicka street was built in open excavation. Hamburg method with Berlin walls was effective for western part of tunnel (along Pawia street). »Politechnika« station was erected in open excavation with Berlin walls for vertical temporary soil support. In the case of »Dworzec Główny« station open wide excavation without soil protection was used for erection of underground part of structure. Finally, information on applied safety systems in tunnel are given.
