Simulations of landslide run-out can avoid the limit of experiment and instrumentation. It can
observe the movement processes in detail. It is essential to the quantitative hazard
assessment for landslide. for the simulation of landslide movement, the primary work is to
establish a landslide model. Although the Particle Flow Code (PFC) is one of the most
widely used program for landslide modeling, it is weak in the pre-processing of building the
landslide model. This limits its application to landslide modeling. As for this, this paper …
