%X Dredger fill sand has small cohesive force, inadequate engineering performance, and is vulnerable to rainfall erosion which leads to subgrade destruction. Used as roadbed filling material, dredger fill sand should be reinforced by inorganic binder. Triaxial tests were carried out on dredger fill sand specimens stabilized with lime and cement to research their strength properties and stress-strain regularity. Test results show that dry density, curing period, and inorganic binder content are positive correlated factors affecting the strength of dredger fill sand; while the delayed time of compaction and the water content are negatively correlated factors. As for salinity, with 3% as a dividing line, when less than 3%, the strength is increased with the increase of salt content; when larger than 3%, the strength decreases with the increase of salt content.
