摘要根据天津永定新河口滩涂地层沙性土分布规律，采用现场标准贯入试验和室内动三轴试验两种方法进行了沙性土的液化判别。

• Based on the distribution regularities of stratigraphic sandy soil in the Tianjin Yongdingxin River estuary area, the in-situ standard penetration test (SPT) method and the indoor dynamic triaxial test method were used to make the sandy soil liquefaction discrimination.
