To investigate methods for designing high-quality shield tunnels by understanding and rationally assessing the actual loads acting on a shield tunnel during its construction and their effects on its segments, the authors monitored the loadsat the site of construction and conducted a three-dimensional FEM analysis usingthe monitored data. This paper describes the kinds of loads that need to be considered as loads that possibly act during construction and the long remaining effects of construction loads, which were determined based on monitored data of segments, and the results of the numerical analysis, which reproduced behaviors of the segments that received loads during construction.
