摘要
基于川藏铁路隧道工程特点,结合特殊地质条件隧道设计施工难题,系统归纳、总结现有高性能支护体系研究成果及国内外相关工程实践经验。从隧道支护设计理念、支护材料特性及构件性能、施工工艺及控制标准等多维度,阐述特殊地质条件下隧道工程高性能支护关键技术,为特殊地质条件下隧道工程支护设计提供参考。
Based on the characteristics of Sichuan-Tibet Railway tunnel engineering and in consideration of challengers from tunnel design and construction under special geological conditions,this paper systematically summarizes the existing research results of high-performance supporting system and relevant engineering practice experience in China and abroad.It expounded the key technologies related to the high-performance support for tunnel engineering under special geological conditions from the aspects of tunnel support design concept,support material characteristics and component performance,construction technology and control standards,which may provide a reference for the support design of the tunnel engineering under special geological conditions.
