Abstract: Taking Fushun Strip Coal Mine Slope for example, the failure mechanism and distortion rule of the slope are analyzed. Based on the creep test of soft layer, a mechanical model of creeping was proposed. Time effect equation of long term strength was established by measuring ultimate strain and strain velocity during the creeping of soft layer. According to the equation, dynamic stability of the slope was evaluated. The results show that the stability was heightened greatly after reinforcement and drain. The model provides a method for predicting and controlling the stability of creeping slope.

Key words: creep test, toppling-displaced mass, dynamic stability, instability prediction
