摘　　要：针对泾河下游河谷段某水垫塘岩质边坡的岩体结构特性和结构面发育情况,依据边坡工程地质资料,在分析边坡岩体结构特征和潜在滑移模式的基础上,利用三维离散元法分析边坡稳定性,并采用极限平衡法对计算结果进行对比验证。分析结果表明,基于三维离散元法的岩质边坡稳定性分析结果合理,在正常和暴雨工况下,边坡安全系数均大于规范要求的安全系数标准。研究成果可为岩质边坡稳定性分析提供参考。Based on the plunge pool rock slope engineering geological data, the characteristics of rock mass structural and the potential failure modes of the slope are analyzed. The 3D discrete element method is used to analyze the slope stability analysis, and the limit equilibrium method is employed to verify the calculation results. The results show that the stability analysis of rock slope based ;~I） discrete element method is reasonable. 1,1 the normal and heavy rain conditions, the safety factor of slope is greater than the standard requirements. The research can provide reference for stability analysis of rock slope.
