摘要:研究目的：随着城市地铁建设日渐增多，地铁施工所面临的穿越各种既有运营线路的问题也随之增多。为了进一步了解盾构穿越既有运营线路的影响，本文根据某城市地铁施工实际情况，主要针对地铁盾构穿越既有铁路线时采取的各项控制措施，以及采取控制措施后各项变形情况进行分析。研究结论：地铁盾构穿越京广线股道群时，为减小对铁路运营的影响主要在于施工中采取的各种控制措施，本文通过本区间穿越期间对沉降进行分析，虽然在盾构穿越期间造成地表、轨枕、道床沉降量较大，但通过各种控制措施合理施工，确保了穿越期间铁路运营安全。
Abstract: Research Purpose:With the construction and development of urban subway, the problems emerge during the metro construction when the shield tunnel traveling existing lines increased. In order to explore the influence when the shield tunnel traveling the operating line, this paper discussed different control measures based on the data recorded during the metro construction in a city and made a concrete analysis of each measure according to the deformation. Research Conclusion:To reduce the effect on the operating line when the shield tunnel traveling track group of the Beijing-Guangzhou Line, the paper made a concrete analysis of settlements of construction area. The study found that although the settlements of ground, ballast and the sleepers is higher than usual, the operation safety was ensured with the help of several control measures.
