Abstract：Aiming at the defects in the existing risk assessment methods, a new model for slope risk assessment was proposed from the angle of risk concept in combination with the matter-element extension method and Markov chain method. The risk matrix was established to complete the integration evaluation from qualitative to quantitative aspects, the field monitoring data were brought into the risk assessment system,and the change rules and trends of slope risk were dynamically tracked and predicted. After fully understanding the risk nature and interrelation, the overall slope risk was dynamically analyzed in the proposed method. The results show that the proposed method can improve the timeliness and reliability of risk assessment results,the prediction results is more accurate and objective,and the proposed method has a good practical application value.
