Mechanical Behavior of Large-Diameter Adjacent Shield Tunnelling Bridge Piles: A Case Study of Chunfeng Tunnel
Source abstract
Abstract
When a large-diameter shield crosses through bridge piles, stress and deformation of the bridge piles caused by tunnel excavation occurs. This is a an exciting topic of engineering research into the construction of subways. We considered an 15.8 m large-diameter shield machine made in China to excavate the Chunfeng tunnel as the background of our research. First, based on the previous engineering experience, reinforcement measures of the shield crossing the bridge piles were investigated. PLAXIS 3D finite element software was used to simulate the process of shield tunnelling through the piles of Hongling Interchange No. 1 Bridge. We analyzed the mechanical characteristics of the piles in the process of shield tunnelling through the bridge piles and evaluated the reliability of the reinforcement measures. Finally, combined with field monitoring data, the accuracy of the model and the rationality of the treatment measures were verified. This research considered a successful case of 15.8 m large-diameter adjacent shield tunnelling bridge piles. Analysis of the stratum and the mechanical behavior of bridge piles in the process of crossing provides a theoretical reference for engineering measures on similar projects in the future.
