摘要
以京张铁路清华园隧道下穿北四环施工为背景,介绍了大直径泥水盾构下穿路堑式城市主干道的综合施工技术,通过检测、评估、三维模拟、施工控制等技术方法,确保穿越过程路面及挡墙沉降控制在标准范围内,保证了施工的安全,可供同类工程参考。
Taking the down-traversing Beisihuan construction at Qinghuayuan Tunnel along Beijing-Zhangjiakou Railway as the background, the paper introduces the comprehensive construction techniques of large-diameter shield down-traversing cutting urban trunk road, ensures the traversing roadbed and retaining wall settlement to be controlled within the standard by detection, evaluation, three-dimension simulation, and construction control to guarantee the safety in the construction, so as to provide some reference for similar projects.
