摘　　要：岩溶的发育程度、上覆岩土体性质是岩溶地面塌陷形成的基本条件;地下水位下降,地表水或降水入渗,震动荷载等动力扰动,是形成岩溶地面塌陷产生的诱发动力条件。本文以山东省泰安市岩溶地面塌陷区为例,讨论了岩溶地面塌陷的产生机理,并从受力情况对其进行了分析探讨,从而提出了岩溶地面塌陷的预测模型。本文还根据研究区的8个塌陷实例对模型进行了检验。结果表明,该模型的计算结果与实际情况基本吻合。The development degree of Karst and the nature of the overlying rock soil mass are the basic formation conditions of the Karst Collapse. Dynamic disturbance such as lowering of groundwater table, infiltration of surface water or rain water and vibration load are the induced dynamic formation conditions of the Karst Collapse. In this paper, we took Tai＇an City, Shandong Province as an example of Karst Collapses, discussed the generation mechanism of Karst Collapse and analyzed it from the mechanical aspects, then established a forecasting model of karst collapse. Then we applied eight karst collapses in Tai＇an City to test the forecasting model. The results showed that the outcome of the model presented in good agreement with the actual situation.
