摘要/Abstract

摘要： 川藏铁路隧道建设面临高海拔、复杂地质条件、恶劣环境等方面的严峻挑战，其中，高海拔环境对隧道施工装备选型的影响尤为突出。为实现川藏铁路隧道机械化建造，以新建川藏铁路雅安至林芝段隧道建设为例，在分析高海拔环境影响因素的基础上，从动力系统、电气控制系统、流体控制系统、空压机性能等方面，重点论述高海拔环境对钻爆法隧道装备作业性能的影响。系统研究并针对性提出在高海拔高寒等极端环境下超前支护、开挖、初期支护、二次衬砌等钻爆法施工关键工序的装备选型建议，如超前钻探及支护设备、凿岩台车、拱架安装设备、混凝土喷射设备等，并提出“破碎机+皮带机”出渣、挖装运电动设备、移动式除尘等新型装备和技术在川藏铁路隧道建设中的应用建议。

Abstract: The construction of the SichuanTibet railway faces numerous challenges such as significant terrain elevation differences, complex geological characteristics, and a harsh climatic environment, among which the high altitude has particularly significant effects on the Sichuan-Tibet railway′s construction. The influence factor of high altitude on construction equipment by drillandblast method for Ya′anLinzhi section is analyzed from the aspects of power system, electrical control system, fluid control system, and air compressor performance to realize mechanized construction of SichuanTibet railway tunnels. Some recommendations for equipment selection of key construction processes of drillandblast construction operations in cold and highaltitude environments, such as advance support, excavation, primary support, and secondary lining, are made. The equipment includes advance drill and support equipment, rockbreaking jumbos, arch frame installation equipment, shotcrete equipment, crusher + belt conveyor mucking system, excavation +  loading + electrical transport equipment, and mobile dedusting equipment.

Key words: Sichuan-Tibet railway tunnel, drillandblast method, highaltitude environment, equipment comparison and selection
