Prediction of Deformation of Adjacent Existing Running Tunnel due to beneath Shield Tunneling
With the rapid development of metro engineering construction in China, the impact of shield tunneling on adjacent existing building has been paid more and more attention in recent years. Taken the Jiulongshan-Dawanglu running tunnel of Beijing Subway No.14 built by shield method as engineering background, a three-dimensional numerical model based on the soil-structure interaction theory is established by using the finite element software ANSYS to simulate the shield tunneling beneath the adjacent existing running tunnel of Beijing Subway No.1. The displacement of the adjacent existing running tunnel is predicted. During the shield tunneling, the vertical deformation of the adjacent existing running tunnel can reach up 2.8 mm, and the horizontal deformation value is about 0.5 mm, which can satisfy the project need and the requirements of relevant standard. The numerical results can be regarded as a valuable reference for the construction.
