为实现川藏铁路高起点、高质量、高标准的建设目标,针对高原长大隧道群在地质、气候、生态等方面的风险和挑战,系统性地开展钻爆法成套装备技术体系研究。首先,对川藏铁路隧道钻爆法施工面临的主要挑战进行系统分析,提出与工程特点紧密结合的高原环境、复杂地质、生态环境、机群协同4方面装备技术需求,并详细阐述对应装备的适应性设计技术。然后,以常规地质标准化配置和特殊地质针对性处置为策略,提出川藏铁路隧道施工成套装备体系的建议方案,以适应川藏铁路一般性及特殊风险隧道建设的需要。最后,针对川藏铁路工程对数字化、信息化管理的更高要求,开展以装备数据为驱动的围岩分级与动态设计、装备机群施工调度、施工质量在线评价关键技术的初步探索。通过建立智能成套装备机群协同作业平台,依托机械化、信息化、智能化为川藏铁路安全、优质、高效、绿色建设提供支撑。
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.
