客运专线大瑶山隧道全断面快速施工技术

武广客运专线大瑶山1#隧道全长10081m，为考虑施工进度及远期运营需要，在中间左侧设置一横洞，横洞长888m。结合施工实际，介绍通过横洞进入正洞后两个工作面施工的设备配套与快速施工技术，包括爆破、开挖、装碴、运输、初次支护、二次衬砌等，为以后类似工程的快速施工提供一定的借鉴。

High-speed Full-face Construction Technology for Dayaoshan Passenger-dedicated Railway Tunnel

No. 1 Dayaoshan tunnel on Wuhan～Guangzhou passenger dedicated railway is 10081m long. For the sake of construction schedule and future operation, an access adit with 888m length is installed at the intermediate point on the left of the tunnel alignment. Through the access adit, two more working faces are provided for the construction of the main tunnel. The equipment matching and high speed construction technology (including blasting, excavation, muck loading and haulage, primary reinforcement and secondary lining) for the two mentioned working faces are presented in the paper, which can provide reference for the high speed construction of similar works in the future.
