Abstract
Many types of countermeasure are applied to prevent rock fall or landslide. While any countermeasures using nets and ropes are made from metal, the fiber material is little used for the rock fence and slope protection work. The construction work becomes difficult in slope using the metal material because of heavyweight of the member. Meanwhile the fiber material is lightweight and flexible, so that it seems that the construction work becomes easy. Because the performance of the countermeasure using fiber material is not clear, the impact resistance test is carried out. This paper shows that it is effective in preventing rock fall.
