摘　　要：饱和松砂地基在瞬时振动作用力下易发生液化,从而导致工程主体的破坏。就砂土液化机理和振冲加固机理进行阐述,并结合埃及塞德港二期集装箱码头结构后方地基处理试验区实践,对振冲处理饱和砂土地基液化风险的效果进行分析评价,为工程设计和施工提供参考依据。Saturated loose sand foundation will liquefy under the force of instantaneous vibration,thereby leading to the destruction of the subject.This paper expounds the liquefaction mechanism and vibroflotation mechanism of sand,and analyzes the effect on eliminating the risk of liquefaction of vibroflotation treatment combining with the ground treatment trial area at the backland area of the Egyptian Port Said Container Terminal Phase II,serving as references for similar projects.

关 键 词：砂土液化机理 饱和砂土 振冲法加固 液化判别方法
