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.
巖溶的髮育程度、上覆巖土體性質是巖溶地麵塌陷形成的基本條件;地下水位下降,地錶水或降水入滲,震動荷載等動力擾動,是形成巖溶地麵塌陷產生的誘髮動力條件.本文以山東省泰安市巖溶地麵塌陷區為例,討論瞭巖溶地麵塌陷的產生機理,併從受力情況對其進行瞭分析探討,從而提齣瞭巖溶地麵塌陷的預測模型.本文還根據研究區的8箇塌陷實例對模型進行瞭檢驗.結果錶明,該模型的計算結果與實際情況基本吻閤.

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.
