Outline of Final Research Achievements

The criteria of calculation conditions and the information of input parameters for rockfall simulations are analyzed from the viewpoint of engineering. Obtained knowledges can be used as basic information for numerical simulations in rockfall disaster prevention. Based on the obtained information, a real rockfall was reproduced to validate the availability of the information. Furthermore, a new method for probabilistic rockfall risk analysis based on numerical simulations was proposed.
