What is 5.vol Loss Determination about?
The document describes a semi-analytical method to estimate volume loss at the tunnel face and ground surface for shield-driven tunnels. The method is based on the principle of minimum total potential energy. It accounts for soil volume changes during ground movement, unlike previous two-dimensional models. The authors analyze how support pressure, tunnel diameter, depth, and other factors influence volume loss at the tunnel face and ground surface. The volume loss at the face decreases with increased suppo
