Abstract

For rational rockfall rock measures, an accurate evaluation of the rockfall behavior is an important problem. Various numerical analytical methods are developed so far, and there are the thing put to practical use. However, the numerical analysis is hardly considered how much predict rockfall behavior precisely. This paper developed a new simulation technique of real rockfall by the Discontinuous Deformation Analysis (DDA) and by introducing the probabilistic technique. The applicability and validity of the simulation technique was verified by applied to the field tests of rockfall. Furthermore, as the practical application, the examination of a rational rockfall protection work for the rockfall disaster of Mt. Fuji was summarized.
