COMPUTATIONAL DESIGN LTD West Axis at limits of Region of Western Macedonia – Design for the Improvement of Road Florina – Antartiko - Prespes The project is about the improvement of the National Road from the Northern City of Florina to the Prespa Lakes Area, a highly touristic site of Northern Greece. The total road length is about 56 Km and the length designed by this project is about 26Km. High Mountain elevations between 750m and 1500m above sea level with very steep slopes and very deep ravines. To this extremely rugged terrain with granite subsoils there will be constructed 17 Valley bridges and an Cut&Cover and this is the subject of the Structural Design of the project. All bridges are precast – prestressed concrete beam structures of total lengths between 80m and 130m. The precast beams are transferred in situ and raised to be placed on the high piers and abutments. They are circular in plan with relatively small radius (95Μ to 140Μ) and have a longitudinal slope of about 6%. The overall width of the deck including the pavements is about 13.00m. They have a single traffic surface with one lane on each direction and barriers on each side. Expansion joints are provided at the abutments. The structural continuity of the deck along the length is provided with a continuity deck slab through the piers. Each pier consists of a pair of circular hollow columns of reinforced concrete and a cap beam on top of each pier which supports the upper structure resting on anchored laminated elastomeric bearings. At both bridge ends, transition slabs in conjunction with the abutments and the abutment wing walls form the transitional backfill. The piers and the abutments are founded on pile foundations. The Survey Design involves the creation of the topographic background for the road design which includes contours and Land marks as : • Local traffic network. • Houses and other small structures (fences, retaining walls, etc.). • Fields and agriculture areas. • Utility networks (Electricity, water supply and irrigation, etc.) • Site elevations The Hydraulics include the design of a network for the safe drainage of the surface of the road and the bridge decks. The project includes 38 cabinet and tubular conduits of various sizes and many wells for the collection of water along the road.
