Dynamic Analysis of Subsea Tunnel Based on the Dynamic Geo-Centrifuge Test


Abstract eng:
The importance of cost-wise effective engineering and construction is getting increase due to the surge of traffic volume in the metropolitan cities. Accordingly, the necessity of the tunnel has large section becomes more critical. Subsea tunnel can be one of the most appropriate solutions to that kind of necessity. The dynamic stability of subsea tunnel is essential against seismic load since it has large section and connection between perimeter lining and interim slab. In this study, dynamic geocentrifuge test was also performed to analyze the seismic behavior of subsea tunnel. Additionally, 3-dimensional dynamic numerical analysis was conducted based on the Finite Difference Method to compare the seismic behavior of subsea tunnel. Seismic joint for dynamic stability and the mitigation of seismic impact on the lining was considered in the modeling and analysis. Consequently, seismic behavior of subsea tunnel showed similar behavior and the mitigation of acceleration, lining displacement and stress were verified successfully.
