摘要：Rockslides are a common and devastating problem affecting miningand other engineering activities all over the world; consequently, therehave been many studies into their prediction and prevention. This studyfocused on a recent rockslide in an open-pit mine in Liaoning Province,China. The stability of the rock slope under excavation and rainfallconditions was monitored using an efficient real-time monitoring system. Afurther numerical analysis was performed using the finite element methodwith Lagrangian integration points (FEMLIP), and two forms of the normalizedglobal second-order work were calculated to analyze the stability of therock slope. In fact for the future it would be very interesting to compare measurements and simulations in real time, and not only to develop backcomputations after failure. The numerical results indicate that the rockslope remained stable during excavation, yet lost stability after subsequentrainfall. Water infiltration, along with a major geological discontinuity,degraded the strength of the weak zone and induced the rockslide. Themonitoring approach presented its robustness and generality, and was worthbeing generalized. The numerical approach proposed the evolution of thesafety factor, the monitoring data were compared, and the mechanism of therockslide was determined. It could be used as an assistant tool for disaster prediction.
