The affects on the construction of super-adjacent spacing twin tunnels using shield tunnel boring machine were considered on the design of segmental linings. For this design, the FEM analysis was used to evaluate the affects of the shield tunnelling method. Moreover, to clarify the behavior of the adjacent segmental lining during excavation of another side of tunnel, the precise monitoring of strain in the segmental linings were carried out. This paper discussed the results of the monitoring and evaluates the satisfaction of the design for segmental lining considering the comparison between the results of analysis and monitoring.
