Soft marine soil deposit is distributed under the sea with many special properties. This type of soil is rarely researched in Vietnam because of the difficult geotechnical investigation under the sea level. In this paper, the experimental laboratories were performed to investigate the geotechnical properties of soft marine soil at Chan May port, Vietnam. The field investigation results indicate that the thickness of soft soil varies from a few meters to more than ten meters. Soft soil has a high value of water content, void ratio, and compressibility and a low value of shear strength. The compression index has a good relationship with water content, liquid limit, and dry unit weight. The unit weight, shear strength, and preconsolidation pressure increase with the increase of depth. These results show that the soil in the study area is unfavorable for construction activities
