摘要
以地面塌陷的地质模式为基础,建立了覆盖型岩溶区地面塌陷的两种力学分析模型——整体垮塌型和土洞渐扩型;讨论了两者的力学形成机制,提出了稳定性分区原则。其分区原则与桂林地区塌陷的统计规律基本吻合。
Besed on the geological models for land collapse, two kinds of me-chanical analysis models-whole land collapse and gradually enlargedcavity were established. Their resulted mechanism is discussed and theclassifying principle of the stability of covered karst terrain is put for-ward.
