| 对于非贯通性结构面的边坡稳定性分析是历来岩质边坡研究的重点和热点.本文利用极限平衡法，对库区的岩质边坡进行分析，分析了岩质边坡中非贯通性结构面出露段位置、结构面的强度参数和结构面贯通率对其稳定性的影响.计算结果表明：当结构面的贯入度和结构面的强度相同时，结构面出露段出现在上部时边坡的安全系数大于结构面出露段在下部，上下部都有出露段时，边坡的安全系数最小.当结构面的出露段位置相同时，结构面的强度参数越大，边坡安全系数的变化就越小. |

| It is research focus and hot spot for stability analysis of rock slope with non-penetrate continuity.Rock slope for reservoir region was analyzed by using limit equilibrium method.Continuity outlet’s location，coefficient of continuity and ratio of continuity penetrate were analyzed for the influence of rock slope stability.The result shows，When the ratio of continuity penetrate and the coefficient of continuity is same.The safety factor of rock slope for continuity outlet ’s location from big to small is upside，bottom and upside-bottom successively.When the continuity outlet’s location was same.The larger of continuity strength coefficient，the smaller of rock slope safety factor’s varieties. |
