The impact of shield tunnels on neighboring buildings during construction has received more attention, while the impact of tunnels on neighboring buildings during operation has been little studied. However, in order to guarantee the safety of the architectures, the influence on adjacent ancient architectures which are sensitive to vibration and displacement should not be neglected during tunnel operation period. In this paper, numerical simulation is used to study whether the vibration and displacement of the adjacent ancient pagoda, Hangzhou White Pagoda, meet the safety control standards during the operation of the shield tunnel. According to the Finite Element Method analysis, judgment on safety of White Pagoda was made. The results of numerical simulation showed that the tunnel operation had a low impact on the adjacent White Pagoda.
