Key Points

The study aims to evaluate the quality of undisturbed clay samples based on volumetric strain during recompression at in situ effective stress.
Samples of marine clay were collected for a port and airport project.
Volumetric strain data were collected and analyzed during the recompression process.
The study discusses the validity of quality assessment based on volumetric strain.
Data on volumetric strain during recompression were successfully collected.
Findings suggest that volumetric strain is a useful indicator of the quality of clay samples.
The validity of assessing sample quality based on volumetric strain is supported by the analysis.

Implication

Assesses clay sample quality via volumetric strain under effective stress, indicating reliability of strength measurement.
