Comparative Study on Seismic Response of Pile Group Foundation in Coral Sand and Fujian Sand
Journal of Marine Science and Engineering, 2020 The physical and mechanical properties of coral sand are quite different from those of common terrestrial sands due to the special marine biogenesis. Shaking table tests of three-story structures with nine-pile foundation in coral sand and Fujian sand ...

Effect of Saturation on Shear Behavior and Particle Breakage of Coral Sand
Journal of Marine Science and Engineering, 2022 Coral sand is the main filling material for the island–reef foundation. Under tidal actions, the saturation (Sr) of coral sand layers varies with the specific depths in the reclaimed foundation. Studying the Sr effect of coral sand’s mechanical behaviors
