Abstract
<p> This research carries out model tests to investigate the dynamic behavior of multi-section cut-and-cover subway tunnels in transvers direction by seismic motion, which has not been fully investigated. A multi-section model tunnel as well as a general single box type one is installed in a soil vessel and it is found that the sectional force corresponds to those obtained by tunnel design. Then, the L2 earthquake motion (Spectrum II) based on design standard for railway structures is applied to the soil vessel. The results show that the bending moment and shear force are comparatively large in the center wall, the tendency is different among the loading direction. Moreover, the results of 3D dynamic finite element analysis for evaluation of model tests shows approximately the same situation and this research gives various findings to establish the seismic analysis method of multi-section cut-and-cover subway tunnels.</p>
