The effects of the construction were considered in the design of segmental linings for very close spacing. In the design, the FEM analyses were used to evaluate the effects of the shield tunnelling method. Moreover, in order to clarify the behaviour of the adjacent segmental lining during the excavation of another tunnel, the precise in-situ monitoring of strain and deformation of the segmental linings was carried out. This paper discusses the results of the monitoring, and evaluates current design method for segmental lining based on the comparisons between the results of design analyses and the monitoring.
