摘　　要：利用安装在动三轴仪上的剪切波速测试装置 ,测试了天津某地区土的剪切波速 ,并在此基础上将室内测试结果与现场测试值进行了比较。研究发现二者的差值与土层埋深。By using a shear wave velocity measuring system fixed on a cyclic triaxial apparatus, the shear wave velocity of clay sampled from an area in Tianjin is tested. By comparison there is a differece between the results of laboratory and field tests. It is found that the differece is directly related to the depth of earth and the content of clay particle.
