| Abstract: | In this paper,shear wave velocity measurning system was developed on existing cyclic triaxial apparatus.The improved system allows for measuring the shear wave velocity of the soil specimen by direct wave propagation.Clay from Tianjin are adopted as test samples.The difference between shear wave velocity obtained in-site and those obtained with the measuring system are discussed.We found the difference was less than 16 percent,and the difference was directly related to the embedded depth. |
