| 摘 要： | 小浪底引水发电洞环形帷幕灌浆，是大坝左岸帷幕灌浆的一部分。论述了环形灌浆的布置、施工程序、施工方法及灌后施工质量检测等。经压水试验检查共64孔，其中只有2个孔大于5Lu，合格率为96．6％，弹模测试岩体波速度均大于3500m／s，灌浆后与灌浆前纵波速度这比在1．1以上，能满足设计要求，帷幕灌浆施工质量好。

| Abstract: | The circular curtain grouting for power tunnels is part of the curtain grouting on the left abutment of Xiaolangdi dam. This paper addresses its arrangement, construction procedure, construction method and quality inspection after grouting. Water pressure test was undertaken for 64 holes, of which only 2 were over 5 Lu. The qualified rate is 96.6%. Elasticity modulus test gave the wave speed in rock mass over 3500 m/s. The ratio of longitudinal wave before and after grounting is over 1.1, which meets the design criteria. The grouting quality is good. |
