摘要
针对乌鲁木齐城市轨道交通1号线穿越的活动断层特点,提出一种综合无砟轨道稳定性好、便于日常巡检和紧急情况下乘客疏散以及有砟轨道便于调整等优点的新型轨道结构设计方案;基于有限元分析方法,评估设计方案的破坏形态;研究活动断层错位时轨道结构的调整、修复方案。结果表明:新型轨道结构设计方案能够满足设计意图,在基底发生空间大变形时能够按设计的破坏形态破坏,且能够满足在活动断层发生瞬时空间大变形破坏后轨道结构可以快速、便捷修复的要求。
According to the characteristics of the active faults where Urumqi urban rail transit line 1 passes through,a new design scheme of ballastless track system is proposed,which is characterized by track stability,convenient tour inspection,quick evacuation in case of emergency,and easy adjustment and ballast track.The failure mode of the new design scheme is evaluated based on FE analysis method.The adjustment and repair scheme of the track structure is researched in case of active fault dislocation.The results show that the new design scheme of track system can meet the functional requirements of track structure during service,and the affected track structure can be repaired quickly and easily once large spatial dislocation of active faults occurs.
