摘要
根据首都机场线采用直线电机牵引系统的特点及要求,对地面线地段的轨道类型进行比选,确定采用长枕埋入式无碴轨道,对无碴轨道路基基础工后沉降进行分析,论述水泥粉煤灰混凝土(CFG)桩复合地基处理。
According to the characteristics and requirements of Beijing Airport Line on which linear motor system is adopted, this paper analyzes and compares the types of tracks for surface sections of the line and proposes ballastless tracks with buried long sleepers. The paper also analyzes the settlements of the ballastless track subgrades after construction and discusses the design of CFG pile composite foundation.
