Numerical Simulation for the Failure Process of Floor with Water Pressure |
| |
| Abstract: | The instable progress of floor with water inrush is simulated with the Stratum Failure Progress Analysis(SFPA)system. Based on the result, the mechanism of instability in the floor with confined water is studied and the instable position is forecasted. Compared with theoretical approach and experiment, SFPA is a new numerical simulation approach to study the problem of instability in the floor with confined water. |
