摘　　要：传统的液化判别方法虽然简便,但各有缺点。陈国民根据上海地区的经验关系,给出了考虑粘粒含量的液化判别式,并给出了液化等级的计算方法。文中比较了扁铲液化判别方法和标准贯入试验的判别结果。实践结果表明:扁铲侧胀试验是一种较好的、有前途的液化判别方法。Although the traditional methods of liquefaction estimation are conventional, there are some shortcomings of these methods. A new formula is recommended to estimate liquefaction by professor chen guomin, which take the clay content into account according to the experience in Shanghai area. The article compares the result of liquefaction estimation between DMT and SPT. The result proves that the dilatometer test （DMT） can act as a better method with boundless prospects to predict the sand liquefaction potential.
