摘要
随着高速铁路建设的快速发展和"走出去"项目的逐步推进,我国自主研发、具有自主知识产权的CRTSⅢ型板式无砟轨道技术将会得到广泛应用。对于高速铁路长大隧道、特高桥梁和深挖路堑,CRTSⅢ型板式无砟轨道施工物流通道和物流活动直接影响施工工期。结合京沈客专特殊地段结构特点和CRTSⅢ型板式无砟轨道物流特点,提出适用于高速铁路长隧、高桥、深堑结构的无砟轨道物流组织模式:对于高速铁路长大隧道、高桥结构,建议采用单线底座通道施工法;对于高速铁路深堑结构,建议优先采用双线底座通道施工法,当条件不具备时,考虑采用双线基面通道施工法,以提高施工效率。
With rapid development of high speed railways and progress of ＂going global＂ projects, the independently developed CRTSⅢ slab track technology will be applied widely. For long tunnels, super high bridges and deep cuttings of high speed railway, the logistics service and activities for laying of CRTSⅢ slab track directly infl uence the construction period. Based on the features of special sections of Beijing-Shenyang Passenger-dedicated Line and logistic demands of CRTSⅢ slab track, the paper promotes the logistics organization model appropriate for the ballastless track of high speed railway structures, e.g. long tunnels, super high bridges and deep cuttings, namely, single line and foundation channel for long tunnel and high bridge construction. dual-line and foundation channel for deep cutting construction, and dual-line and base channel shall be considered when the conditions are not available to improve the construction efficiency.
