摘    要:运用能量守恒等基本原理量化各危岩块的相互作用,进而得到各危岩块的等效弯矩计算公式,于是可将复杂的群体危岩简化为单体危岩进行研究。运用断裂理学和损伤力学基本原理研究了危岩的崩塌机理,得到了危岩崩塌时间计算方法。根据陡崖上各危岩块的崩塌规律验证了危岩链式规律并为陡崖及其附近的地貌形成提供了理论依据。

关 键 词:岩石力学  危岩  崩落机理  群发性  损伤与断裂力学

Abstract:The physiognomy of cliff was formed by chained regularity of perilous rocks' macro-chain and micro-chain,so the reciprocity of perilous rocks and the reciprocity of macro-chains in the process of study on the mechanism of multiple rocks on the cliff collapse must be considered.It had quantified the reciprocity of perilous rocks through the conversation of energy which could gain the equivalent bending moment's calculation formula,so the complicated multiple rocks can be predigested to a single perilous rock...
Keywords:rock mechanics  perilous rock  the mechanism of collapse  multiple  damage and fracture mechanics
