An analytical investigation for compensation solutions in underground excavation at depth
The excavation compensation method (ECM) is used in deep tunneling to manage large deformations by applying high-prestressed active support immediately after excavation. Under asymmetric in-situ stresses, tunnel convergence becomes non-uniform, causing NPR cables to carry different axial forces even when the same pre-p...
