Research on the Strength Characteristics of Coastal Hydraulic Fill Organic Saline Marine Mud

The experimental dataset in this study was obtained from a series of unconsolidated undrained (UU) triaxial compression tests conducted on coastal hydraulic fill organic saline marine mud. The tests were designed to investigate the effects of confining pressure, dry density, salinity, and organic matter content on the strength behavior of the soil. Confining pressures of 100, 200, and 300 kPa were applied to simulate different in-situ stress conditions, while dry density and chemical composition were systematically controlled to reflect typical engineering states of reclaimed coastal soils.
