| Abstract: | Combining with actual conditions of Dujiaoqu No. 1 tunnel, the paper briefly describes the tunnel excavation control technologies of strong-weathered thin-layer surrounding rock, which includes monitoring and measuring, pre-reinforeing surrounding rock, three-stage excavation method and smooth blasting technology. Praetiee proves that： the excavation control technology is reliable and effective, which guarantees the tunnel eonstruetion safety, speeds up construction schedule, and improving eonstruetion quality. |
