The research was conducted to apply the DDA to rock-fall simulation. The following properties are clarified. For rock-fall analysis, it is important to consider the behavior of the rock-fall movement. 1: The velocity of the gravity-center of the rock-shape is dependent on the normal component of the impact velocity. 2: The variation of the trajectory of falling rocks after the rebound is dependent on the shape of the falling rocks. For the consideration of variation in velocity and trajectory, Monte Carlo Method was introduced to the rock fall analysis by DDA.
