Aiming at the collapse and failure of high dangerous rock in Zhaojiaya, Xingshan County, numerical simulation methods were used to simulate the stability, evolution law and movement characteristics of the regional dangerous rock mass, so as to obtain the movement track, bounce height and impact energy of the collapsed rock. The results show that the Zhaojiaya dangerous rock has good stability under natural conditions. Under continuous rainfall or rainstorm, the fissure water gradually permeates, and there is the possibility of collapse and failure of the main control structural plane. After the collapse and destruction of the dangerous rock, most of the fallen rock will stay on the slope, and a few of the fallen rock will stop on the road at the foot of the slope after the collision and rebound. Combined with the actual situation of the site and RocFall simulation, the governance measures of "danger clearing + slope leveling + passive protection net" were proposed. The research results can provide reference for similar disaster control projects of high dangerous rock collapse.
