| 中文摘要:水工隧洞高压固结灌浆的目的是加固隧洞围岩、封闭隧洞周边岩体裂隙，提高隧洞围岩的整体性和抗变形能力，增强围岩抗渗能力和长期渗透稳定性。主要介绍了引水隧洞在未进行混凝土衬砌的条件下实施高压防渗固结灌浆施工的试验及其成果，为该类洞段灌浆设计和施工提供依据。 |

| Abstract:The functions of high-pressure consolidation grouting for hydraulic tunnel are strengthening the tunnel wall rock, sealing rock cranny around the tunnel, increasing the wall rock’s integrity and capability of anti-distortion, strengthening the wall rock’s impermeability and long-term seepage stability. This article has mainly introduced the tests and the effects of high-pressure consolidation grouting works for diversion tunnel without concrete liner, and provided the basis for grouting design and construction of the tunnel engineering. |
