Seismic response analysis of underground structures at coral sand sites is a critical component in ensuring the structural safety of island reef engineering. Current experimental studies in this field have primarily focused on unidirectional seismic excitation. To investigate the seismic response differences under multidirectional seismic loading, this study designed a series of shaking table tests under unidirectional, bidirectional, and triaxial loading schemes. The seismic responses of underground structures and coral sand foundations were compared under different loading conditions, including boundary effects, ground and structural accelerations, Fourier spectra, and structural strains. The results indicate that the soil–structure system exhibits responses in the non-excitation directions during the shaking table tests. Compared to the excitation direction, boundary effects are more pronounced in the non-excitation directions, with vibrations in these directions primarily concentrated in the high-frequency range (16–20 Hz). The ground acceleration amplification factors in the X-, Y-, and Z-directions in different loading directions are 0.9–1.3, 1.4–2, and 3.4–3.7, respectively, showing significant differences. Under triaxial loading, the peak strain in the underground structure is significantly higher than that under unidirectional loading. Full article
