Abstract: This paper briefly introduced the topographic, geologic conditions, engineering and hydrological geology aspects of a syncline rock slope in Guiyang City. The stability aspects of this slope are also qualitatively and quantitatively evaluated and the parameters for the slope stability analysis are appropriately determined. In order to evaluate the effect of buildings at the crest of the slope on the stability, the syncline slope after the excavation is analyzed with planar sliding method. The supporting scheme is selected based on the engineering conditions and construction costs comparison of each measure.

Key words: Syncline Rock Slopes, Slope Stability, Supporting Measures
