Experimental Study on the Influence of Particle Gradation on the Resistivity Characteristics of Saturated Coral Sand
Due to the action of hydraulic sorting, coral sands in different engineering site areas usually have different particle gradations.

| description | Due to the action of hydraulic sorting, coral sands in different engineering site areas usually have different particle gradations. To explore the impact of particle gradation on the resistivity characteristics of saturated coral sand, an experimental study was conducted on the effects of the coefficient of uniformity <i>C</i><sub>u</sub>, the mean particle size <i>d</i><sub>50</sub>, and the fines content <i>F</i><sub>c</sub> on the resistivity characteristics of saturated coral sand. The results show that under the same porosity, the resistivity of saturated coral sand gradually decreases with the increase in <i>C</i><sub>u</sub>, increases with the increase in <i>d</i><sub>50</sub>, and first decreases and then increases with the increase in <i>F</i><sub>c</sub>. When <i>F</i><sub>c</sub> equals 20%, the resistivity of saturated coral sand is at its minimum. To eliminate the influence of pore fluid on the resistivity characteristics, a structural factor was introduced to evaluate the resistivity characteristics of saturated coral sand, and a prediction model for the structural factor of saturated coral sand considering the gradation effect as a function of porosity was established. |
