根据甘肃省肃南县酥油口水库历经两次防渗处理后的渗漏问题进行分析，对垂直帷幕灌浆方案进行了分析论证，没有达到防止渗漏的目的，建议采用斜孔帷幕灌浆方案，该方案对减小水库渗漏的作用和效果显著，达到了预期的目的，同时也为病险水库坝基、坝肩的斜孔帷幕灌浆防渗处理技术方面探索了一条新路子，积累了一定的经验。

Based on the analysis of the leakage after two impermeable treatments of Suyoukou reservoir in Su'nan County, Gansu Province, the vertical curtain grouting program was proved to fail to prevent leakage. In this study, the inclined-holes curtain grouting program was recommended. This program could significantly reduce the reservoir leakage and fulfill the desired objective. At the same time, it provided a new way and accumulated some experience for the inclined-holes curtain grouting technology at the foundation and abutment of the dangerous dam.
