Abstract

Shield tunneling method, one of the excavation methods, expands of demand in underground space at great depth. In underground space at great depth, the ground is stable, and axial force generated in shield tunnel excels. Therefore, in case of using steel segments at great depth shield tunnel, we must take local buckling at main girder into consideration. In this study, we prove local buckling at main girder of steel segment in great depth shield tunnel by experiment and Finite Element Method.
