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.
