| 摘 要： | 本文在分析辽宁省已有的岩溶塌陷灾害资料的基础上，对其形成条件进行了讨论，认为可溶性岩石，复杂的断裂构造，一定厚度的覆盖层是产生岩溶塌陷的必备条件，过量抽取地下水，降雨和地震是诱发因素，文章最后对可能发生这类灾害的危险区作了预测。

| Abstract: | Based on the analysis of the disasters of karst pitfall in Liaoning province,the cause of karst pitfallhas discussed in this paper. The research result shows that soluble rock,complex fault structures and covering layer with cer-tain thickness are necessary condition for the formation of karst pitfall.The induced factors producingthe pitfall include over pumping ground water,rainfall and shock.The prediction for dangerous areato cause karst pitfall has presented as well. |
