Deformation characteristics of open-pit slope affected by excavation loading
Aiming at the stability of open pit slope under excavation unloading, the deformation characteristics of slope under excavation unloading are studied by numerical simulation and theoretical analysis method, and a practical fast identification method of slope stability is proposed. Taking the slope of the dump along the south end slope of the first mining area of Heidaigou Open-pit Mine as an example, the stress and deformation characteristics of typical section under the condition of step excavation of the end slope are analyzed by finite element numerical simulation method, and the characteristics of slope deformation in time and space are summarized. The open-pit side under the condition of excavation and unloading is analyzed theoretically. The cumulative effect of slope deformation and the principle that the deformation does not increase orderly when the slope is destroyed by instability are compared with the results of monitoring and safety factor calculation, which shows that the relevant conclusions and methods are applicable to engineering practice.
