Experimental study on anisotropy of saturated coral sand under complex stress conditions
Yantu gongcheng xuebao, 2022 Anisotropy is the inherent property of coral sand. A series of undrained monotonic shear tests are carried out on the saturated Nansha coral sand by using the GDS hollow cylinder torsional shear apparatus.

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 is crucial for the stability of the reclaimed foundation of island–reefs.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Experimental study on dynamic shear modulus and damping ratio of coral sand from Nansha Islands
Rock and Soil Mechanics, 2020 The physical and engineering mechanical behaviors between coral sand and terrigenous sandy soils are considerably different. To study these behaviours, a series of undrained multistage strain-controlled cyclic triaxial tests were conducted on saturated
