GEBZE-ORHANGAZI-İZMIR MOTORWAY GABION RETAINING WALL PROJECT

As a result of the investigations made in the project area, it was determined that the correct solution for slope stabilization would be the Gabion retaining wall. The Gabion Retaining Wall was determined as a solution when the parameters of ease of finding stones in the application area, application speed, the technical approach to the solution of the slope problem, the weight wall requirement, being economical, architectural appearance, earthquake resistance and need for a flexible structure are considered. Gabion Retaining Wall is 7 m high and has 4 m heel width. The Stone sizes used are between 125 mm and 250 mm and the unit weight of the stone is 25 kN / m³. Since there is a 30% void ratio in gabion structures, 17.5 kN / m³ unit volume weight was taken as a basis in the design. In the project, box gabions are made of heavy galvanized coated double twisted wire mesh in 8X10 mesh type and 2.7 mm thickness produced in accordance with international standards in Maccaferri’s Düzce factory. For the design, EUROCODE 7-8 norms were used to determine the load combination in both seismic and static analysis. The analysis program used in the design is Maccaferri Macstars W 2000. 4300 m³ gabion has been manufactured and the total manufacturing period is 75 days.
