| 中文摘要:两河口水电站初期导流洞发育有较多断层及绢云母板岩夹层，尤其是f25、f3、f8系列、f4、f28等断层由多条次级错动带组成，破碎带宽度大，岩体完整性差，围岩极不稳定。为了确保导流洞运行安全，需对导流洞洞内Ⅳ类、Ⅴ类围岩区域进行固结灌浆施工并根据要求进行灌浆试验。主要介绍了固结灌浆试验施工工艺。 |

| Abstract:There are many faults and sericite slate sandwich development in initial diversion tunnel of Lianghekou hydropower station, especially f25, f3, f8 series, f4, f28 and other faults are composed of multiple secondary dislocation bands with wide fracture zone, poor rock integrity and unstable surrounding rocks. In order to ensure the safe operation of the diversion tunnel, Ⅳ and Ⅴ-class surrounding rocks inside the diversion tunnel should have consolidation grouting; and according to the requirement, grouting test should also be made. The paper mainly introduced the process of consolidation grouting test construction. |
