Abstract: For the sutra cases of Shijing Mountain based on the investigation in site, the lithology, terrain and the geologic structure are analyzed. The potential slopes with rockfall are confirmed initially. Four typical profiles are selected on the slopes and surveyed by BJSD-2B laser profiler. With the results of the numerical simulation, the locations A~F on the profiles are confirmed as the potential rockfall sources with the bigger possibility to fall. The volumes of blocks situated at A~F are gained in site. On the basis above, the kinetic characters(run-out distances, bounce height, kinetic energy and the translational velocities )of the six blocks are predicted and analyzed by the help of the rocfall software. The simulation results show that the rockfall of the block D threatened the life safety of the tourists less than other blocks, but it could destroy the sutra cave No.7 greatly. Oppositely, the rockfall of the other five blocks would threaten the life safety of the tourists greatly, but they wouldn’t destroy the relevant caves. The suggestion that the key locations and blocks should be reinforced as quickly as possible is given.

Key words: sutra caves of Shijing Mountain, rockfall hazards, numberical simulation
