論文概要(Abstract)
This paper details a typical simulation method and analysis of the
manner of rockfall. Fundamental idea is concretely shown to consider
the roughness of the slope surface to reproduce the state that is close
to the real slope. A treatment method of the roughness at the moment of
the collision between a rockfall and a slope was developed. The method
expressed the roughness of the slope by adding an angle in the normal
vector of the triangular plane. The validity of proposed simulation
method becomes clear by the application to rockfalls on a simple slope.
