摘要
利用安装在动三轴仪上的剪切波速测试装置,测试了天津地区粘土的剪切波速。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最大不超过13%,并与土样埋深有直接关系。
In this paper, shear wave velocity measuring 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 was 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 13 percent, and the difference was directly related to the embedded depth.
