摘　　要：本文以洛阳地铁2号线王城北路站至机场路站区间左线侧穿右线大断面暗挖隧道近接施工为背景,针对盾构近接大断面隧道施工风险进行分析研究,制定了相关技术和管理措施,确保已完成的暗挖隧道不发生收敛形变超限,拱顶沉降超标等问题,为类似盾构近接施工提供参考。This paper investigates the shield tunneling technology used for side-passing large-span existing tunnels in urban rail transit,taking the side-passing construction of the left tunnel beneath the right tunnel in the section between Wangcheng North Road Station and Airport Road Station of Luoyang Metro Line 2 as the background.The study analyzes the risks associated with shield tunneling near large-span tunnels and formulates relevant technical and management measures to ensure that the existing excavated tunnels do not experience excessive convergence deformation or excessive crown settlement.This research provides references for similar shield tunneling projects.
