Flexible protection barriers have not been as widespread as retaining walls in Japan, and it is difficult to confirm their effectiveness using full-scale tests because of safety management issues. However, the flexible protection barrier will become more useful tool in slope failure protection as new designs are developed. Here, we report on an experiment conducted in Switzerland in 2008. This experiment utilized full-scale collapse where soil flowed down-slope and the load was measured at the barrier. The flexible protection barrier safely caught 140 m3 of soil. According to the calculated flow velocity determined using high-speed video cameras, flexible protection barriers could endure loads on many slopes in Japan, although they require a ‘catching space' downstream of the barrier to collect collapsed soil.
