摘要:云台山景区地质条件复杂,在受到构造活动、地质应力作用和人类活动等共同影响的条件下,发育了一定量的危岩体。在总结各景点危岩体的特征和分布的基础上,分析了危岩形成原因。结果表明:红石峡景点内的危岩体主要为拉剪倾倒型单体危岩、拉裂坠落型单体危岩和群体危岩,其形成原因主要受到断层和人类活动影响;沟谷景区内的危岩体主要为群体危岩,是构造活动和风化等地质应力共同作用形成的;茱萸峰景点和旅游干线内的危岩体以群体危岩为主,其形成主要是由于人类活动影响形成的。与此同时,提出了研究区危岩体相应的综合治理措施,其中除沟谷景区主要用到SNS被动防护外,其它各景点以主动防护为主。

Abstract:There are a certain amount of perilous rocks in Yuntaishan scenic region.Their occurrences are caused by the complicated geological conditions and the combined impact of tectonic activity,geologic agent and human activities.The paper analyses the forming reasons of perilous rocks based on the features and distribution of perilous rocks in Hongshixia spot,Ravine spot,Zhuyu peak spot and tourism lines of Yuntaishan scenic region.It turns out that the perilous rocks in Hongshixia spot is mainly toppling perilous rock under tension-shear,falling perilous rock under tension with the influence of the faults and human activities,structure activity and weathering geologic agent cause the forming of perilous rocks in the Ravine spot,dangerous rocks in the Cornel Peak spot and tourism lines is mainly the human activity.Furthermore,the paper puts forward the corresponding comprehensive treatments.Among the treatments,passive safety netting system can be used in the Ravine spot,and the treatments of active protections can mainly be used in other spots.
