Abstract:

With respect to the forming mechanism of soil displacementand construction features of the shield tunnel, the concept of equivalent circular zone is supposed. With the help of the measured displacements, the parameters of the equivalent circular zone can be obtained exactly. This paper uses ANSYS finite element method to deduct the parameters of the equivalent circular zone, which can provide reference for the designingand construction of shield tunnels.
