扁铲侧胀试验用于液化判别的探讨

Discussion on Dilatometer Test Used for Liquefaction Estimation

扁铲侧胀试验是一种非常有用的原位测试方法。结合南京的工程实践和国内、外的经验公式,提出了临界水平应力指数(KDcr)的计算方法,并以此来进行液化判别和计算液化等级。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。

The dilatometer test （D）MT） is a very useful in-site testing method. Combining with the engineering practice in Nanjing and empirical formulas at home and abroad, the calculating method of the critical horizontal stress index （KDcr） is put forward; moreover, the liquefaction estimation and calculation of liquefaction grade are made by this method. The result proves that this test （DMT） is a better method with good prospects for liquefaction estimation.
