Abstract

In this research, it was aimed to investigate the potential landslide induced by spillway construction activities at Durhasanlı reservoir site located in Manisa province of Turkey and provide a feasible stabilization measure. Since the site reconnaissance revealed that some deformations on spillway concrete members and the development of tension cracks at the head of hillside on the right bank of spillway, five inclinometers were immediately placed at critical points and the possible slope movement was observed for 40 days. It was found out that the mass movement were going on at a rate of about 0.1 mm per day. With the help of inclinometers’ data, the depth of sliding mass was also determined. Accordingly, based on geotechnical properties obtained from surface and subsurface investigations, a number of slope stability analyses were carried out taking into account such factors as the tension cracks, earthquake loading, reduction of slope weight and pile reinforcement. As a result, the secured solution for the stability of mobilized slope was suggested by terracing the hillside, pile reinforcement, and effective drainage system.
