Abstract

A source localization test is conducted in the rare earth mine slope and the velocity-free localization method with active sources correction is used to determine the source positions. The peak ground acceleration (PGA) is used to characterize the response caused by the disturbance source, based on this the dynamic response and disaster development regulation can be qualitatively evaluated. The PGA values are obtained through the forward model using random forest and gradient boosted decision tree algorithms. The relative risk level of the slope is then divided according to the statistical distribution of PGA. The hazard level of the slope under dynamic disturbance at different positions is presented and the hazardous areas are determined.
