摘　　要：文章运用三维数值模拟的方法对复杂的岩溶塌陷机理及过程进行了系统性研究,探讨了Flac3D三维数值模拟应用于岩溶塌陷的模拟技术及方法,为岩溶塌陷的客观评价及预测开辟了有效途径。在研究中成功地应用数值模拟的方法时地下水面以上的土洞塌陷机制进行了模拟,并对岩溶区的典型地质概化模型的致塌机理进行验证。In this paper, the mechanisms and processes of the Karst collapse were studied systematically by making use of the numerical simulation, and the Flac-3D was applied to the simulative technique and methods of the Karst collapse. The study on the problems will supply more objective assessment and more efficient forecasting warranty for Karst collapse research. In the research, the numerical simulating method was successfully applied to simulating the collapse mechanism of soil hole above groundwater. The typical geological conceptive models of Karst collapse were verified in the article.
