In this study, the soil-structure interaction impact of a 3-hinge Concrete Modular Underground Arch (CMUA) is simulated using Abaqus/CAE. The results indicate that Abaqus/CAE is an effective tool for seismic simulation of the CMUA. Besides, the structural damage under the earthquake impact can occur locally on lining structure or its surrounding at the soils that is influenced significantly by the interaction and contact between structural parts as well as linkages of segments.
