Mesudiye (Ordu) state road (Km: 18+000 - 18+360) geotechnical investigation and stability analysis of reinforced earth walls

In this study, geotechnical investigation and stability analysis of the strip reinforced earth retaining wall constructed on the left side between T2 Ilisar Tunnel and T3 Mesudiye Tunnels on Gölköy-Topçam Separation Mesudiye State Road (Km: 18+000 - 18+360) within the borders of Ordu province were carried out. The wall in question is located on the left side of the route; the length of the wall is 370 m and the height of the wall is 30 m. Considering the data obtained within the scope of the study, based on the analysis of the project under study, the design of a palletized reinforced earth retaining structure, which is considered to be under the influence of traffic loads, was studied. As a first step, the design behavior for the existing geotechnical conditions was investigated. The lane length and density data obtained from the internal and external stability investigations were used in PLAXIS software for calculations over a width of 1m. Vertical and horizontal displacements and tensile forces on the reinforcement strips were measured. It was determined that these displacements and forces were within acceptable limits.
