This article presents a comprehensive approach to assessing the stability of excavation pit slopes in seismically active regions, based on the integration of remote sensing data using unmanned aerial vehicles (UAVs) and numerical modeling using the limit equilibrium method.
The study focused on a pit up to 60 m deep, located in a zone of increased seismic activity in the Kyrgyz Republic. A high-precision digital elevation model was generated using aerial photography with a Phantom 4 RTK UAV, which was used to develop a geomechanical calculation model.
The stability calculation was performed using the Morgenstern-Price method, taking into account the physical and mechanical properties of the soils and pseudo-static seismic impact. The slope stability coefficient was assessed, potential slip surfaces were identified, and the most dangerous deformation zones were determined.
It was shown that taking seismic impact into account significantly reduces the stability coefficient and requires adjustments to the slope design parameters. The proposed approach improves the reliability of slope geomechanical assessments and can be used in engineering and geological surveys and design in complex geodynamic conditions.
