  要:危岩体是指陡峭边坡上被多组结构面切割,在重力、风化营力、地应力、地震、水体等作用下与母体逐渐分离,稳定性较差的岩体。其对工程建设的潜在威胁严重,在对危岩进行调查的基础上,本文结合危岩的相关形态与结构特征,考虑有关影响危岩变形因素,分析危岩体的形成机制,进一步对危岩体进行评价和预判,其目的是提高危岩体的勘查和评价水平,为危岩治理工程提供可靠的依据。

Abstract: Dangerous rock mass is a rock mass cut off on steep slope by multiple structural planes. It is gradually separated from the parent body under the action of gravity, weathering force, ground stress, earthquake and water body and has poor stability. The potential threat to the engineering construction seriously, based on investigation of dangerous rock, related to the morphology and structural characteristics of this combination of rock, considering the factors influencing rock deformation, analysis of the formation mechanism of dangerous rock mass, further evaluation of the dangerous rock body and anticipation, the purpose is to improve the level of exploration and evaluation of dangerous rock mass and provide a reliable basis for rock engineering.
