This paper reports depth proifles of the vane shear strength of soft marine clays in Shanghai based on the results of 12 engineering investigation surveys. The relationship between depth and the ratio of undrained strength to effective overburden stress is analyzed, and the range of observed values is given. The relationship between the plasticity index and the ratio of undrained strength to effective overburden stress was also analyzed. Finaly, the correlation between FVT strength and the speciifc penetration resistance of CPT was determined.
