随着城市的建设与发展，也需要对城市中岩质边坡稳定的风险评估进行不断的研究。对某城市住宅区附近的边坡，运用基于不连续岩土体材料的基本属性和岩体的地质力学参数，评估了对岩质边坡稳定性影响最大的参数以及边坡的失效概率。根据确定性分析和概率分析法分析，最可能会导致平面滑动而破坏。此外，利用敏感度分析法对各影响因素之间的关系及其对安全系数的影响进行了分析。结果表明：边坡坡角、孔隙水压力和节理组产状对安全系数的影响很大，不同的参数和研究区安全系数之间属于非线性关系，继而提出提高城镇中岩质边坡稳定性的有效方法。

With the construction and development of cities, risk assessment of rock slope stability in urban areas also needs to be researched continuously .Based on the fundamental properties and geo‐mechanical pa‐rameters of discontinuous rock mass, the most influential parameters of the rock slope stability and the slope failure probability in the residential area in a certain city are evaluated in this paper .According to the deterministic and probabilistic analyses, it could most potentially cause plane slide and failure .Moreover, the relationship among the influencing parameters on instability and their impact on safety factors are ana‐lyzed by sensitivity analysis method .The results show that the slope dip, pore water pressure and joint set dip are highly influential on the safety factors .There is also a nonlinear relationship between different pa‐rameters and safety factors in the studied area. Thisstudy presents an approach for reducing the risk of this rock slope stability in urban areas .
