Field vane shear strength, s_<u(v)> is presented for seven Japanese soft marine clays with the plasticity index, I_p ranging from 20 to 120. The value of s_<u(v)> was compared with that obtained from unconfined compression tests which is a standard for determining the shear strength of cohesive soils for design use in Japan. Several researchers have reported that the vane shear strength normalized with the consolidation yield pressure, s_<u(v)>/p'_c is dependent on I_p. However, the s_<u(v)> /p'_c values obtained from the present study were generally constant with I_p' with values ranging from 0.25 to 0.35. Bjerrum's correction factor, μ is commonly used to determine the shear strength for stability analysis from the vane shear strength. The shear strength modified by this method, however, was found to be considerably conservative for Japanese marine clay, when compared with the unconfined compressive strength that has been proved to provide an appropriate shear strength for practical use in Japan.
