<p>The deposition and fine content in soil can significantly affect the granular soil particle fabrics. A series of resonant column tests and undrained cyclic shear tests were conducted on saturated coral sandy soils with various particle orientations (<i>φ</i>) and fine contents (FC). The maximum shear modulus (<i>G</i>₀) first decreases and then increases as <i>φ</i> increases, and reaches its minimum at <i>φ</i> = 60°, whereas the <i>G</i>₀ decreases with the increase in FC (0–30%). The influences of <i>φ</i> and FC on the liquefaction resistance of saturated coral sandy soils are related to cyclic stress paths. A remarkable finding is that a unique form of the relationships exists between the unit cyclic stress ratio (USR) and the number of cycles required to cause failure (<i>N</i>_f), where <i>N</i>_f is defined as the number of cycles corresponding to the occurrence of 2.5% generalized shear strain (<i>γ</i>_ga) in the specimen. For constant values of <i>φ</i> and FC considered in this study, the USR decreases with the increase of <i>N</i>_f in the form of a power law independent of cyclic stress paths. By converting laboratory element test conditions to field conditions, another significant finding is that the test data pairs of USR_{15, field} in cycles and the overburden stress-corrected shear wave velocity <i>V</i>_s1-field in the field for coral sandy soils fall to the right of the field case-based liquefaction triggering curves derived from clean silica sands, which is probably due to the irregular particle shapes of coral sand. Insights obtained in this paper offer a new perspective for evaluating the liquefaction triggering potential of coral sandy soil sites.</p>
