This study was performed to investigate the engineering geological and geotechnical characteristics of the rock material and rock mass, and to provide appropriate support recommendation and stabilization techniques along the two autoroad tunnel projects (Ilıksu 1 and Ilıksu 2) located along the Antalya-Alanya autoroad. The tunnel grounds were classified according to the Q-system, RMR and NATM, and support systems and stabilization techniques were determined. The deformation moduli and shear strength parameters were obtained by using the Geological Strength Index. In order to determine the stability of the portal and cut slope sections, kinematic and limit equilibrium analyses were performed for the discontinuous rock slopes. Static stability analyses of irregularly jointed, highly foliated and deformable soil-like lithologies were analyzed by slope stability softwares, and recommendations were made regarding the required support systems. The interactions of the support systems with the rock mass were analyzed through finite element analysis.
