Bener Dam diversion tunnel is located in two rock units such as andesite and andesite breccia. Based on the engineering geology investigation, the tunnel consist of andesite breccias with moderate and poor rock mass quality.
Geological and engineering geology conditions are used as the basis for stability analysis of excavation methods and determining primary tunnel support systems. The stability analysis of the openings and tunnel supports was cariied out using and empirical and numerical method approach.
