岩质边坡稳定性分析边坡稳定性的一般理解是边坡中的滑动体沿滑面破坏，即抗滑力与滑动力之比。当比值等于1,为极限平衡状态；大于1，为稳定状态；小于1，为不稳定状态。这是一种岩体破坏的稳定性概念。有一些工程，对边坡变形有严格的要求,变形量不能超过工程允许的变形量,更不允许发生边坡破坏，应以建筑物允许变形量为标准评价边坡的稳定性，以应变理论为基础，进行岩质边坡稳定计算。还有一些工程，对边坡变形量和破坏虽没有严格的要求，但是，要防止边坡破坏后发生快速滑落；在这种条件下,应以滑体速度为标准评价边坡的稳定性,以功能定理为基础，计算岩质边坡滑落速度。分析方法是以岩体结构为基础，判断边坡变形破坏的形式，应用岩体力学的基本理论和方法，做出定量评价，为边坡工程设计提供科学依据。分析步骤如下：①应用岩体结构分析方法，划分边坡岩体结构类型，并根据类型判断边坡破坏形式：块状结构边坡，由多组结构面组合,发生块体或楔形体破坏（图1）；层状结构边坡，由单一的层面或断层组成，沿平面发生滑动破坏（图2）；碎裂结构边坡,由多组密集的结构面组合,沿多组结构面发生追踪破坏（图3）；散体结构边坡，一般是指严重风化岩体，破坏形式近似为圆弧形（图4）。②在岩体结构分析的基础上，根据岩体的受力条件，如岩体自重、爆破力、工程作用力、地下水作用等，用力学分析方法进行计算。计算方法有平面的极限平衡解析法；楔形四面体的极限平衡分析法；赤平极射投影与实体比例投影相结合的图解法；边坡岩体应力和应变状态的有限元法。这些方法都能给出边坡稳定性的定量评价。③在力学分析的基础上，从地质成因方面着重分析岩石性质、结构面的性质、地下水动态性质等因素随时间的变化，判断边坡稳定性的变化趋势，为确保边坡稳定提出加固措施。根据以上步骤的综合分析结果，选定边坡设计方案，并进行技术论证和经济比较、确定合理的稳定坡角。为了防止边坡发生变形破坏和提高稳定坡角，可采取如下加固措施：①直接加固。挡墙及护坡、抗滑桩、滑动面混凝土抗滑栓塞、锚杆及钢绳锚索；②间接加固。边坡中巷道及钻孔疏干地下水，地面排水及地面铺盖防渗，削坡减载卸荷；③特殊加固。麻面爆破，压力灌浆（见岩体加固）。
