Stability of foundation rock mass beneath the A4 rescue platform in the Ruyifeng scenic spot, Yangshuo, Guilin

This work makes an assessment of the stability of the rock mass beneath the A4 rescue platform during the construction of the Ruyifeng scenic spot project in Yangshuo， Guilin. It builds on the combination of the methods of field surveys and theoretical analysis including stereographic projection qualitative analysis， the limit equilibrium method and finite element numerical simulation. The results show that the rock mass beneath the A4 rescue foundation is in an unstable state thus needs to be reinforced. Additionally， we puts forward the reinforcement treatment measures so as to provide theoretical support and scientific basis for the treatment of later possible collapse of the dangerous rock， which would be a certain reference for the stability research of similar rock masses in karst areas.
