An improved criterion for the threshold of motion of sand to gravel‐sized bioclastic carbonate sediments under steady unidirectional flow: Insights from coral skeletal grain experiments

open access: yesSedimentology, Volume 73, Issue 1, Page 103-122, January 2026.
ABSTRACT The threshold of motion of bioclastic carbonate sediments is fundamental to understanding sediment dynamics in coral reef systems, while there are currently few studies on its prediction. In this study, laboratory experiments were conducted on five sediment beds composed of coral skeletal grains coarser than 2 mm, subjected to steady ...

An Experimental Study on the Seismic Response of Vertical and Batter Pile Foundations at Coral Sand Sites

open access: yesJournal of Marine Science and Engineering
Liquefaction and earthquake damage to coral sand sites can cause engineering structure failure. Both testing and analyzing the seismic response characteristics of pile groups on coral sand sites are highly important for the seismic design of engineering ...

Sand Liquefaction Through Volume Decrease Potential

open access: yesSoils and Foundations, 1976
ABSTRACT Cyclic triaxial shear tests were performed on granular materials with a variety of grain sizes and uniformity coefficients to determine the effect of grain composition on the liquefaction potential of cohesionless soils. In place of the conventional measure of relative-density as a density index the difference between the current and minimum

Evaluation model for soil liquefaction based on soil classification charts and its indices from cone penetration tests

open access: yesYantu gongcheng xuebao
The static cone penetration test (CPT) is an internationally used technique for potential evaluation of soil liquefaction in the world. The common method of CPT is based on the equivalent pure sand and only applicable to sand and low plastic fine-grained
