A full understanding of the geotechnical properties of deep sea soil is necessary for ocean engineering construction, and the basis is the evaluation and testing of undisturbed deep sea soil. Therefore, to investigate the geotechnical properties of deep sea soil, a series of experimental tests were conducted in this study. Furthermore, the test results of the deep sea soil were compared with that of the soft dredger fill. The results showed that deep sea soil comprised of high contents of clay minerals and fine particles as well as high compressibility and low strength. Compared with soft dredger fill, the mineral composition and microscopic characteristics of deep sea soil is greatly different, which is the main reason for the differences in their geotechnical properties. This study provides great support for understanding and evaluating geotechnical properties of the deep sea soil and provides an effective method for the preparation of deep sea soil samples.
