Abstract

To study the structural deformation risk caused by the construction of a double-track shield tunnel passing under the terminal building, this paper takes the Zhengzhou-Xuzhou Intercity Railway passing under the airport terminal building project as the background and uses the Midas GTS NX finite element software to simulate the construction process of a double-track shield tunnel passing under Terminal 1 of Xinzheng Airport. By comparing and analyzing with the on-site monitoring results, the reliability of the finite element model was effectively verified. The influence of shield tunnel construction on soil deformation and pile foundation response was analyzed and compared with the monitoring and control standards of relevant specifications. Studies show that the peak of surface settlement caused by double-track construction converges towards the midpoint of the axes of the two tunnels, and the maximum settlement increases from 2.19mm for a single track to 3.11mm. The development law of the vertical displacement of the foundation is mainly related to the relative spatial positions of the left and right tunnels as well as the crossing progress. After the double-track shield tunnel was connected, the maximum lateral differential settlement of the pile foundation at the verification point was 0.63mm, and the maximum longitudinal differential settlement was 1.13mm, both of which met the specification requirements and the operational needs of Terminal 1. This study deepens the understanding and recognition of the construction process of double-track shield tunnels and can provide a reference for similar tunnel projects.
