Abstract:  To achieve the highstarting, high quality and high standard construction of the SichuanTibet Railway, a systematic study has been conducted on the complete set of drillandblast 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 drillandblast construction of the SichuanTibet 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 completeset equipment system is proposed for tunnel construction to meet the tunnel construction demands of the SichuanTibet railway. Last, for the higher requirement on the digitization and information management during the SichuanTibet railway construction, a preliminary exploration of key techniques for rock classification and dynamic design, equipment group collaborative scheduling, and constructionquality 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, highquality, efficient and green construction of the SichuanTibet railway through mechanization, information and intelligentization.
