Abstract. Rockslides are a common and devastating problem affecting mining
and other engineering activities all over the world; consequently, there
have been many studies into their prediction and prevention. This study
focused on a recent rockslide in an open-pit mine in Liaoning Province,
China. The stability of the rock slope under excavation and rainfall
conditions was monitored using an efficient real-time monitoring system. A
further numerical analysis was performed using the finite element method
with Lagrangian integration points (FEMLIP), and two forms of the normalized
global second-order work were calculated to analyze the stability of the
rock slope. In fact for the future it would be very interesting to compare measurements and simulations in real time, and not only to develop back
computations after failure. The numerical results indicate that the rock
slope remained stable during excavation, yet lost stability after subsequent
rainfall. Water infiltration, along with a major geological discontinuity,
degraded the strength of the weak zone and induced the rockslide. The
monitoring approach presented its robustness and generality, and was worth
being generalized. The numerical approach proposed the evolution of the
safety factor, the monitoring data were compared, and the mechanism of the
rockslide was determined. It could be used as an assistant tool for disaster prediction.
