PHYSICAL MODEL EXPERIMENTS OF ORDU-GIRESUN AIRPORT, TURKEY

Abstract

Ordu-Giresun Airport, which has been constructed recently, being an example of the aviation sector of Turkish transportation network, is a project having marine structural aspects due to the construction at the sea by filling and in this workout physical model experiments of the project are evaluated. 3000-meters-long runway and the other superstructures of the airport, the first example of construction of such a structure by filling in the sea in Turkey, is to be protected by a breakwater of 7435 meters long. ‘First Cross Section’ has been prepared by using experimental formulas and artificial neural network and ‘Second Cross Section’, being the alternative of the first one has been planned. Yet, both cross sections have similar characteristics, they have berm heights in such a manner that ‘First Cross Section’ enables the structure to be constructed from the sea, whereas ‘Second Cross Section’ makes it possible from the land. Both cross sections are aimed to be evaluated in terms of stability, wave overtopping and economy through the hydraulic model studies performed at the Hydraulics Laboratory of Turkish Ministry of Transportation, Maritime Affairs and Communication. Starting from design stage (computation of design wave characteristics, physical model experiment under different wave conditions on different structure alternatives) to construction stage the engineering studies is presented with comparisons and discussions.
