Takavar and Ebtehaj tunnels as part of Haraz highway are located in southwestern Damavand mount. Statistics show enormous financial and human damages in this route because of rockfall. Geological and topographical conditions, caused to the intensity of rockfall, because most of heights in this area covered by Damavand Trachyandesitic lava flows. In this study Rockfall Analyst (RA) software used to analysis risk modeling of rockfall in three-dimensional. In such a model, the spatial distribution of frequency, height velocity and energy of falling or rolling rocks are calculated. Then the layers in the same velocity, energy and height and the weight, were analyzed and finally 9 risk-prone regions were identified. However, except one of them, other areas need engineering solutions to drop the risk of rockfall.
