Using PLAXIS 2D, it is possible to simulate the construction process of tunnels with a sprayed concrete lining (NATM) and account for the three-dimensional arching effect within the soil and the deformations around the unsupported tunnel face. The method that considers these effects is the called the Convergence-Confinement method or β-method.
In this coffee corner, we will:
Introduce this method in PLAXIS 2D using two different approaches
Discuss their similarities and differences
Demonstrate the workflow in PLAXIS 2D using a NATM tunnelling example
