| Abstract: | In this paper, the mechanisms and processes of the Karst collapse were studied systematically by making use of the numer-ical 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. |
