The metal liners having anchor bolts and ribs are designed to protect sleeve part of sabo dams, water-course floor, and debris bar- riers from scouring and impact loading of rocks. A design method, independent of impact cyclic loading patterns, is suggested considering the energy absorption capacity of the metal liners. INTRODUCTION Because of the avalanche of gravels and rocks in debris flow, the collision of rocks on the sleeve part, debris barriers, and water-course floor
