摘要
本文分析了地下采空情况后认为，山体采空侧动，软弱夹层为决定性条件；其变动范围、速率、规模与性质，与地下采空有关的复合应力场有关。经对观测资料分析、仿真模型试验与仿真数值模拟的对比研究，揭露了顺倾山体的“复合临空面”条件下，“复合变动”的“复合应力场”。
Based on analysis of the structural characteristics of low angle rock layer,this paper particularly deals with the mechanical properties of weak intercalation in the slope.It is considered that the weak intercalation played a leading role and the compound stress field is a basis in the lateral sliding of the mountain body.Furthermore,the lateral sliding process and characteristics of mountain body associated with underground excavation collapse have been studied using the geomechanical modeling and elastic-plastic finite element method and the 'Compound stress field' of ' the compound displacements' in 'compound air surface' conditions of mountain body about the slope conform to dip associated with underground excavation are expounded.
