Estimating Volume Loss for Shield-Driven Tunnels Based on the Principle of Minimum Total Potential Energy

open access: yesApplied Sciences, 2022
Volume loss is an important method to estimate ground movement during tunnelling. However, volume loss is usually estimated by empirical methods, especially for volume loss at the tunnel face, which is a three-dimensional problem.
