title = "Effect of construction sequence of three-arch tunnel on center structure—numerical investigation",
abstract = "This paper concerns the behavior of 3-Arch tunnels constructed in difficult ground conditions. A three-arch tunnel section adopted in a railway tunnel construction site was considered in this study. A calibrated 3D finite element model was used to conduct a parametric study on a variety of construction scenarios. The results of analyses were examined in terms of load and stress developed in center column in relation to the side tunnel construction sequence. The effect of the side tunnel construction sequence on the structural performance of the center structure was fully examined. Fundamental governing mechanism of three-arch tunnel behavior is also discussed based on the results.",
