 In order to predict the time of slope failure during an excavation, a full-scale model slope was built, and the deformation of the slope surface was monitored during slope excavation. The surface displacement rapidly increased with the elapsed time after the excavation, and the relationship between the displacement and elapsed time included an exponential function just before collapse. Based on the results, by computing the inverse of the velocity of the slope surface displacement, a warning signal can be provided 7 min before collapse. In addition, we determined that this method can apply to the data obtained by extensometer, distortion meter, and clinometer.
