中文摘要：花山岩画区的危岩体的存在严重危及古岩画的保存和游客的安全,使得旅游业遭到重创。为了对区内危岩体状态做出评价,并为其后期治理工程提供依据,通过对岩画区的环境地质条件和病害成因的调查,结合危岩体的形态和结构特征,分析得出了区内危岩体崩塌破坏的三种模式为倾倒式崩塌、错断式崩塌和拉裂式崩塌,并提出了不同破坏模式的力学模型。应用极限平衡法对不同破坏模式的危岩体进行了稳定性计算分析,得出区内危岩体大部分处于欠稳定状态,须进行治理。最后提出了危岩体的防治原则与措施。

英文摘要：Because of the existence of dangerous-rock collapse in the protection zone of the cultural relic site of Huashan rock art, the safety of visitors and the integrated conservation of the rock painting have been seriously threatened. In order to evaluate the states of the dangerous rock and provide a scientific basis for the later-stage conservation , by investigating of the geological condition and the cause of geological hazard, the author analyzes the factors that influence the formation of the dangerous-rock and the mechanism of slumping and summarizes that there are three patterns of slumping, including unstable toppling, staggered breaking and pull-splitting land failure. The stability of partial dangerous-rock with different damaged patterns was calculated with the method of limit equilibrium. According to the calculation, most of the dangerous-rock was under an instable situation, and needed to be renovated. Finally, some measures and principles were put forward to prevent and restore the dangerous-rock.
