For the evaluation of strength and construction area for rock fall protection wall and fence, data related with rock fall characteristics such as falling velocity, rolling angular velocity, falling trajectory, jumping height, horizontal spread. and impact force are necessary. Particularly, jumping height and horizontal spread of rock fall are necessary for the decision of construction height and horizontal width of protection wall and fence. Practical rock fall test is difficult to be carried out because of surrounding conditions, although the practical test is desirable along the relevant slopes. For this reason, 2-dimensional numerical simulation on rock fall has been used for the evaluation of rock fall behaviors. But, 3-dimensional rock fall trajectories could not be obtained by the two dimensional analysis. Recently, authors have developed three dimensional rock fall simulation program and have confirmed that reasonable falling velocity, rolling angular velocity, penetration depth, jumping height, traveling distance and others could be calculated compared with observed data. It was found that falling behaviors of stick shape block were different not a little from those of massive and plate shape blocks. Authors have considered that this 3-dimensional rock fall simulation program could be used practically.
