在研究危岩所处的区域环境地质条件和危岩失稳诱发基础上,分析了危岩卸荷带的特征和各危岩单体的结构特征。采用赤平投影法和极限平衡法对该区2个代表性的危岩单体进行定性分析和定量评价。经分析,在暴雨和地震工况下均处于欠稳定或不稳定状态,并根据危岩单体的具体特征,提出了裂缝填埋、削方减载和清表喷锚的治理措施。

Unstable rock instability is one of the frequent geological disasters after the "5.12"earthquake.In this paper,on the basis of the study to the regional geological condition and unstable rock instability of dangerous rock zone,the author analyzes the unloading zone characteristics and the structural characteristics of the monomer dangerous rocks.The stereographic and limit equilibrium methods have been used to qualitatively and quantitatively analyze to two representative monomer dangerous rockmasses.As a result,they both rendered less stable or unstable state in heavy rain and seismic conditions.According to the specific characteristics of dangerous rockmass,it puts forward some control measures such as land filling the cracks,cutting side load shedding and clearing the table spray anchor.
