Firstly, data processing method based on gray theory is used to change acoustic emission information into prediction data. Then prediction data is transformed into essential format of cusp catastrophic model by the least squares principle curve fitting and differential coefficient homeomorphous change. Finally, the gray and catastrophic prediction model is put forward to forecast failure time of rock slope.

Based on the total potential energy principle, the cusp catastrophic model for instability and failure of deep-buried tunnel surrounding rock is established. Through the observed data of settlement values of typical section vault of deep-buried tunnel and the sudden threshold values of displacement of each monitoring section, the variable values of vault settlement function are obtained, and the stability of deep surrounding rock in tunnel is decided.
