Stability Evaluation of Abandoned Dreg Site Slope of Yangqu Hydropower Station in Huanghe River

Taking the Yellow River Yangqu Hydropower Station as the research object, on the basis of engineering geological survey and numerical calculation, the engineering geological conditions around the abandoned dreg site and the scale of the abandoned dreg site were found out, and the deformation and failure characteristics of the abandoned dreg site were analyzed. The stability of the abandoned dreg site is analyzed and calculated, and specific management and protection measures are put forward to ensure the safety and stability of the abandoned dreg site, which provides a basis for the stability evaluation of the abandoned dreg site.
