摘　　要：随着城市地铁建设的不断发展,轨道交通建设越来越复杂多样,随之而来的施工风险也越来越突出。以北京地铁17号线太阳宫站及其附属1/2号换乘通道、西坝河站—太阳宫站区间正线为研究背景,借助数值有限元软件,采用三维有限元模型分析及现场实测对比模拟了穿越既有线变形演化机制及其控制要点,并基于此提出了一套针对穿越过程施工控制措施要求及建议。以期为后续类似地铁穿越工程提供一定技术参考与借鉴。With the continuous development of urban subway construction,rail transit construction is becoming increasingly complex and diverse,and the construction risks that come with it are also becoming increasingly prominent.Based on the research background of Beijing Metro Line 17 Taiyanggong Station and its affiliated 1/2 transfer channel,as well as the main line between Xibahe Station and Taiyanggong Station,using numerical finite element software,a three-dimensional finite element model analysis and on-site measurement comparison were used to simulate the deformation evolution mechanism and control points of crossing the existing line.Based on this,a set of requirements and suggestions for construction control measures during the crossing process were proposed.To provide certain technical references and references for similar subway crossing projects in the future.
