摘要
胶州湾海底隧道海域段隧道轴线穿越两组断裂带、9条断层,断层及其影响带裂隙发育,地下水丰富且受海水补给。注浆技术的研究是为探讨快速注浆工艺,确保注浆质量。根据不同的围岩条件,文中采用不同的注浆方式,使围岩加固与防水效果明显改善,既提高了施工进度,又确保了工期和施工安全。
In waters section of Kiaochow Bay Subsea Tunnel,tunnel axis crosses 2 fracture zones and 9 faults,with cracks in fault and the affected zone,rich underground water supplied by seawater.The grouting technique studied in this paper is to probe into rapid grouting technique in order to ensure grouting quality.According to different surrounding rock conditions,different grouting methods shall be applied for improvement of rock reinforcement and waterproof effect,which improves construction schedule and ensures construction period and safety.
