Abstract: While a spectacular natural landform has formed in Guilin due to the special karstic topographies, many geo-hazards have also encountered consequently. This paper presents the rock fall hazards evaluation methods in Guilin area. The potentially dangerous rock cliff formation, lithology, tectonic formation and failure modes are evaluated and analyzed. Throughout the quantitative stability evaluation, the rock failure potentials in this area could be divided into three types: sliding, toppling and falling, the commercial Rocfall software was used to simulate the rock trajectory, direction of the rock fall and rebounded height. This paper provides the potential mitigation measures such as the static blasting and passive protective rockfall net.

Key words: dangerous rock mass, damage, formation mechanism, stability analysis, mitigation measures
