Research conclusions: The calculation and test results show that The various members of the separated passive protective screen can bear the load more evenly and reasonably because the screen is separated with the steel column due to the special design of the supporting ropes connection with the steel column. When holding up the falling rocks, the steel ropes can move freely. In this way, the stress concentration can be reduced, the impact force on the steel column can be cut, the transmission property of the impact force can be enhanced, the protective property can be improved, the cost can be saved and the maintenance works can be reduced. This method can be widely used in protective works for the railway slope.
