Abstract: To achieve the highstarting, high quality and high standard construction of the SichuanTibet Railway, a systematic study has been conducted on the complete set of drillandblast technology systems, considering the risks and challenges of long and large tunnel groups in plateau areas, such as geology, climate and ecology. First, the main challenges of the drillandblast construction of the SichuanTibet railway tunnel are analyzed. The equipment technical demands closely connected with engineering characteristics are proposed considering plateau environments, complex geology, ecological environments and equipment group coordination. The corresponding equipment adaptive research and development design technology are discussed. Second, based on standard configuration for conventional geology and targeted treatment for special geology, a completeset equipment system is proposed for tunnel construction to meet the tunnel construction demands of the SichuanTibet railway. Last, for the higher requirement on the digitization and information management during the SichuanTibet railway construction, a preliminary exploration of key techniques for rock classification and dynamic design, equipment group collaborative scheduling, and constructionquality online evaluation driven by equipment data is carried out. The established complete set of intelligent equipment and collaborative operation platform can provide support for the safe, highquality, efficient and green construction of the SichuanTibet railway through mechanization, information and intelligentization.
Key words: SichuanTibet railway tunnel, drillandblast method, intelligent equipment; intelligent construction
