摘要： 对贵阳市某顺向岩质边坡工程从地形地貌、地质构造、工程、水文地质条件等几个方面进行概述，用定性、定量分析对边坡稳定性进行讨论研究，对边坡稳定性计算参数进行正确取值，确定坡顶建筑物对边坡的稳定性影响，采用平面滑动法，对边坡开挖后的稳定性进行了计算，并根据边坡工程地质条件、经济效益等综合考虑确定本边坡的支护设计方案，其成果可供类似工程稳定分析及支护设计时参考。

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
