Slope Stability Evaluation Based on Uncertainty Measurement Theory
The evaluation model for slope instability in open - pit mine is established with uncertainty measurement theory. According to the importance of the causes affecting slope stability, nine indexes of three categories, namely, geological structure, hydrogeology, rock mass structure, slope height, slope angle, angle of internal friction, vibration velocity of blasting particle, seismic intensity and average annual precipitation, are selected to set up an evaluation system. Linear measurement function is constructed, the weight of each evaluation index is defined by the objective assignment method, and the level of slope stability is determined by combining the multi-index comprehensive measurement vector and the confidence identification criterion. Engineering applications shows that this evaluation model has certain reference value for the stability analysis of open-pit mine slopes and mine safety management.
