摘　　要：以厦门市某典型工程为例,应用数值模拟方法分析了双线隧道采用不同施工步序条件下,既有条形基础建筑物和隧道结构的变形特征。研究结果表明,综合分析施工步序对既有建筑物和隧道结构产生的影响,通过对先施工小断面隧道后施工大断面隧道的施工顺序进行优化,可明显减小建筑物和隧道结构的变形。Taking a typical project in Xiamen as an example,this paper analyzes the deformation characteristics of the existing strip-shaped foundation buildings and the structure of double-track tunnels under different construction steps by numerical simulation.The research results show that the deformation of buildings and tunnel structures can be significantly reduced by optimizing the construction sequence of small-section tunnels before large ones.
