Study on construction loads during shield tunneling using a three-dimensional FEM model
This study monitored the behavior of segmental rings, and made a three-dimensional FEM analysis of shield tunnels to grasp the effects of loads on segmental rings during shield excavation. The study defined the boundary condition for three-dimensional FEM analysis based on the results of monitoring of the behavior of segmental rings, and estimated the pressure of the tail seal of the shield acting on segmental rings. The results were applied to three-dimensional FEM analysis to evaluate the effects of varying alignments and boundary conditions on analysis results.
