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.
