摘要
本文通过对覆盖型岩溶区薄顶板无充填溶洞岩溶塌陷成因机制的分析 ,提出其塌陷稳定性可以用“盖层土体 -薄顶板无充填溶洞力学系统”的稳定性来解释 ,并分析了盖层土体与薄顶板溶洞之间通过应力传递和质量传输的互动作用。
Based on the analysis of the genesis of the caves with thin roof in the covered karst areas,this paper suggests that the stability of the ground surface overlying caves can be evaluated by the principle of the dynamic system of “covered soil karst caves with thin rocky roof”. In addition, this paper discusses the interaction between covered soil and thin cave roof through stress and mass transmission.
