Karakolithos tunnel into a flysch formation
Summary This study is concerned with the theoretical provision for a confrontation of a support system in tunnels and underground cavities in soils incapable of supporting themselves such as flysch. Such soils could also include crushed or decomposed rocks, clays, shales and sandstones. This paper refers to the ways of calculating the virgin and mobilized stresses of the flysch and to the ways of determining the most suitable location for the axis of the tunnel. The results came out from the construction of three tunnels in flysch in Greece; two near Parnassos mountain and the third in Crete. The average length of each of the three tunnels was 350 m, with an oval section. The Karakolithos tunnel was bored at a maximum depth of 40 m below the surface while the other two which were between 50–200 m have caused several problems.
