Introduction
The Convergence-Confinement Method (CCM) is a widely used analytical approach in
tunnel engineering that helps in understanding the interaction between the
surrounding ground and the tunnel support system during excavation. This method
is particularly useful in the design and construction of tunnels in rock masses,
where the behavior of the ground and the effectiveness of the support systems
need to be carefully evaluated to ensure stability and safety.
In this series of articles, we are going to discuss these following concepts in CCM:
