| Research Abstract |
Rock-fall hazard assessment is indispensable procedure in maintenance of roads and rail tracks. So, a simple and quantitative evaluation of the hazard is needed. From this point of view, several methods based on vibration measurements have been presented. In this study, we proposed a new method to estimate toppling acceleration of a rock mass based on the horizontal-to-vertical natural frequency ratio of microtremors. We applied the method to rock masses and showed that the estimated toppling accelerations were consistent with results obtained from the method proposed by other authors.
