  Rockfall countermeasures are very important in order to keep the safety of railway transportation. As one of the most typical rockfall protection barriers, we aim at the development of a wire gauze with excellent deformability and new rockfall protection barriers of simple structure. Then, static loading tests for wire nets are carried out to study the relationship between dimensioning and deformation characteristics. In addition, a new model net fence, which is expected to have large deformation than that of conventional nets, is tested. As a result, it it proved that the absorbed energy of new fences is larger than that of conventional ones.
