Guanyinge unstable rocks are located in Red Army Bridge Scenic Area of Luding County. Above and below the Guanyinge are unstable rocks, which are fracture, broken and dangerous. Guanyinge unstable rocks directly affect the safety of scenic spot and threat scenic construction and other residential buildings nearby. Through the analysis on the formation mechanism of Guanyinge rocks and basic characteristics, the characters are mastered and the stability is quantitatively analyzed and calculated. The results show that there is a high probability of rocks caving under rainstorm or earthquake and other unfavorable factors. According to the characteristics of the dangerous rock body, a comprehensive scheme of “lattice anchor” and “support anchor” are taken for the lower part and the upper part respectively to remove the hidden danger and accumulate experience for hazardous treatment.
