The project area is located in central Greece, to the west end of Orthris mountain, south of Xiniada basin and NW of Sperhios basin. The tunnels, having general direction SE-NW, are part of the new double-track railway line connecting Athens to Thessaloniki. Visit www.malios.gr and www.intecsa-inarsa.esThe geological formations of the area are distinguished in five main units depending on their lithology and engineering geological characteristics. These units, from the poorest - in terms of geomechanical behaviour - to the more optimum are alluvial deposits, schist-chert formations and flysch (semi-rock formations), breccia-conglomerate deposits, peridotites and dolerites of the ophiolite complex and limestones.Tunnel SS5 has a total length of 432.5 m, with underground excavation 370 m in length and a cut-and-cover entrance of 35.5 m long and a cut-and-cover exit of 27 m long. The excavation cross section area ranges from 116.35 sq m to 120.03 sq m when horse-shoe shaped and from 138.16 sq m to 149.44 sq m when approximately circular. The effective cross section is 78.95 sq m. NATM will be applied for the construction of SS5 and, depending on the rockmass conditions, either full face or sectional excavation will take place. The support elements are rockbolts, steel arches, shotcrete with or without fibres, fiberglass anchors for support of the tunnel face, as well as bolts and fore poling. Tunnel SS6 is a twin tunnel with total length of underground excavation of 12,780 m. Regarding the entrance area, the right branch consists of a cut-and-cover of 17.2 m long and a cut-and-cover of 14.5 m long before the underground excavation whereas the left branch consists of a cut-and-cover of 18.5 long. Regarding the exit area, there will be a cut-and-cover of 107.5 m long for each branch as well as a cut-and-cover of length 522.35 m on the right branch and 521.35 m on the left branch. The distance between the two axes of the tunnels ranges from 25 m up to 110 m.Between the two branches, there will be connecting tunnels at 500 m intervals. The excavation cross section area ranges from 36.84 sq m to 37.34 sq m when horse-shoe shaped and from 42.66 sq m to 51.37 sq m when approximately circular. The effective cross section is 20.81 sq m. NATM method will be applied for them either with full face excavation or sectional excavation. The excavation cross section area ranges from 80.5 sq to 86.7 sq m when horse-shoe shaped and from 94.84 sq m to 111.16 sq m when approximately circular. The effective cross section is 53.02 sq m. NATM will be applied for the construction of SS6. Depending on the rock mass conditions, the excavation will be either full face or sectional. The excavation will be carried out by mechanical means or drill and blast. The support categories of the tunnel are distinguished between stiff and yielding support. The former, sectionally excavated, are either approximately circular or horse-shoe shaped, with or without forepoling, whereas the approximately circular profile can be with temporary invert or not. The yielding support categories will be constructed either with full face or sectional excavation, with or without forepoling. The support for both categories (stiff and yielding) include anchors, steel arches, shotcrete with or without fibres, bolts and forepoling for the stability of the tunnel face. The project also includes the construction of two side access adits (Moschokarya tunnel and Agios Stefanos tunnel), 970 m and 750 m long respectively. The excavation cross section area ranges from 48.21 sq m to 49.79 sq m when horse-shoe shaped and from 53.4 sq m to 67.9 sq m when approximately circular. The effective cross section is 22.7 sq m. NATM method will be applied and the excavation will be either full face or sectional. The tunnel will have either horse-shoe shaped or approximately circular cross sections whereas at places yielding support will be applied. Mechanical excavation or drill and blast will be required for excavation. The support includes anchors, steel arches and shotcrete. At places, the tunnel face will also be temporarily supported and additional support may be required by means of bolts and forepoling. A prequalification tender has already started. The project is expected to start within the year 2007 and it will take four years for its completion.
