The purpose of this study is to develop a rockfall protection fence with maintainability that does not require the replacement work of parts even after rockfall capture. To inspect the performance of the protection fence, full-scale experiments and numerical analysis were carried out. In this study, a series of impact test on the fence which had a post height of 3.5 m and length of 15 m were conducted to evaluate adequately and precisely the absorbable capacity of the impact energy. After that, the protection fence exhibited an outstanding capacity for dissipating the impact energy from 107 kJ to 320 kJ.
