摘要
以远安县"一炷香"危岩体为研究对象,在现场地质调查研究和危岩体变形监测工作的基础上,对"一炷香"危岩体的形成机制和稳定性进行研究,得出以下结论:"一炷香"危岩体基座表面裂隙发育,岩体较为破碎,变形特征明显,崩落方位南、南偏东方向可能性较大;危岩体现状处于欠稳定—不稳定状态,预测其发展趋势为不稳定,在采空区变形、塌陷以及外动力作用下,危岩体失稳可能性大。
In this paper,on the basis of field research and geological survey of rock mass deformation monitoring,researched its mechanism and stability. The results show that： fracture development in surface of the perilous rocks base,broken deformation significantly,caving range south,south easterly direction likely; stratigraphy lithologic assocation of different hardness,regional structural geological conditions,karstification and mining activities formed the perilous rocks masses; perilous rocks was in an understable to unstable,its development trend is unstable. Under the action of goaf deformation,subsidence,and external force,the perilous rocks in a state of instability that increased the probability of downward.
