GEOGRID WRAPPED AROUND AND VEGETATED REINFORCED WALL APPLICATIONS IN THE VILLAGE OF OLYMPIC GAMES IN UNIVERSIADE 2005 IZMIR TURKEY

摘要

23rd University Olympic Games had been hold in Izmir in August 2005. This organization which is accepted as an important opportunity in most of the countries is achieved after great efforts of Izmir Municipality. As a part of this organization, a village for the athletes is constructed in a valley of Uzundere, Izmir. The apartment buildings,which are sold to individual buyers after the completion of the games, are spread out in a very wide area. In the slopes of the valley, green walls with geogrid reinforcements are used as a solution to form stable sides, prevent slope flows during precipitations, and other kinds of slides. Also, an aesthetical presentation of the village was a target to be attained. In order to achieve the goals of the project, geological, geophysical and geotechnical investigations are carried out. The heights of the geogrid reinforced retaining walls in the area are between 5.0 and 10.0 meters and they are constructed using uniaxial and biaxial geogrids with reinforced earth technique by a wrapping system and the geogrids are vegetated to get the green walls or in other words living walls. In this study the mentioned geogrid walls are explained both in the scope of construction and the costs. These applications are also accepted as interesting and cost effective by the Izmir municipality administrators.
