Abstract: This study addresses the stability and treatment issues of high-steep mixed slopes at the Bamboo Industrial Park in Huitong County, employing a multi-method coupling analysis combining the Limit Equilibrium Method (Bishop's method) and the Stereographic Projection Method. Quantitative calculations indicate that the slopes are in a marginally stable to basically stable state under natural conditions (Fs=0.986-1.214), but become unstable under saturated conditions (Fs=0.743-0.903), revealing that rainfall infiltration is the dominant triggering factor. Stereographic projection analysis further identifies multiple sets of unfavorable structural planes in the rock slopes, which are prone to wedge-shaped collapses and planar sliding. Based on this, a differentiated "zoned and classified" comprehensive treatment strategy is proposed, constructing an integrated technical system of "support and reinforcement - three-dimensional drainage - ecological restoration - full-cycle monitoring". This provides a complete solution from accurate evaluation to safe treatment for similar complex slope engineering projects.
