| Abstract: | Characterized by high water content, porosity and sensitivity, marine sediment is easily disturbed and loses water in the processes of transporting the samples and storing them. So, the results by measurement in lab tend to deviate from the true properties of the marine sediment. After comparing the results of mechanical property measured in lab and those tested in-situ on the core samples obtained from the sediment in Yinggehai Sea, we find that the drilling depth, water depth and shear velocity affect the results obtained by in-situ test. Several suggestion have been put forward to calibrate the mechanical results by in-situ test, which will contribute to further applying the methods of in-situ test to marine sediment. |
