摘要
厦门翔安海底隧道是我国大陆地区第一座大断面的海底隧道。隧道所处地质条件复杂,海域地段存在多处风化深槽,岩体主要为全、强风化花岗岩,岩体强度低、自稳能力差。介绍了F3风化深槽地段的施工总体方案,重点阐述风化槽的注浆工艺和开挖支护方法。
Xiang'an undersea tunnel of Xiamen is thought of the first large section tunnel in China's Mainland.The tunnel is located in complicated geological condition with a great deal of weathered deep troughs,the serious weathered granite,low strength rock body and terrible self-stability.The total construction plan of F3 weathered deep trough section and related technology methods of grouting,excavation and supporting were also mentioned and analysed in the paper.
