桂林市穿山公园西侧存在的危岩隐患共有数十处，根据危岩体结构特征和变形破坏迹象，分析了危岩体的3种破坏机制：拉裂―滑移式、拉裂―坠落式、拉裂―倾倒式三种基本类型。在此基础上，运用能量守恒定律和运动学规律研究危岩体失稳落石运动特征。结合 RocFall 软件对落石运动进行模拟计算，对崩塌落石的途径、方向、跳跃高度，影响范围进行验证，与理论计算结果吻合。结合施工条件，采用清除浮土及危石，岩壁上安装 SNSGPS2主动防护网加固，坡脚安装 SNSRX050被动防护网来拦截落石，确保公园内游客安全。

Tens of dangerous rock bodies with hidden danger were found in the west of Chuanshan Park in Guilin.According to the structural characteristics of the dangerous rock bodies and signs of deformation, this paper analyzed 3 different types of failure mechanisms of the dangerous rock bodies:pulling-apart-gli-ding type,pulling-apart-falling type and pulling-apart-overturning type.The paper studied the kinetic char-acteristics of destabilized falling rock bodies by applying law of conservation of energy and kinematics regu-larity.The results of simulating computation of the movement of the falling rocks by software RocFall and verification of methods,directions,bouncing heights and influence area of the falling rocks were consistent with theoretical computation results.In consideration of the construction conditions,the paper suggested that the eluvial soil and dangerous rocks shall be removed.Moreover,for the safety of the visitors of the park,active protection fence SNSGPS2 should be installed on the rock face to reinforce it and passive protec-tion fence SNSRX050 should be installed at the foot of the hill to intercept any possible falling rocks.
