我国从1979年就开始了用剪切波速预测轻亚粘土液化势的研究,利用现场勘测获得的剪切波速资料,按经验作图法给出了八度地区的液化判别界线和判别式。自Dobry按应变法原理提出用剪切波速预测砂土液化势以来,我国也开展了类似的研究工作,提出若干判别方法和判别式。Dobry方法的一个重要缺 Since 1979, China began to use the shear wave velocity to predict the liquefaction potential of light sub-clay. Using the shear wave velocity data obtained from the site survey, the liquefaction discriminant boundary and discriminant formula of the octave region were given by empirical plotting method. Since Dobry proposed the shear velocities to predict the liquefaction potential of sand in accordance with the principle of strain method, China has also carried out similar research work, and proposed several methods and discriminants. An important lack of Dobry method
