摘　　要：阐述了砂土地基的液化机理,分析了在工程结构物附加应力作用下砂土地基的影响区域与压缩再密实过程,给出了附加应力作用下砂土地基液化的进一步判别方法。指出在基础周围和过渡应力区Ⅱ存在液化薄弱区,是工程抗液化处理的重点防范区域。In this paper, the liquefaction mechanism of sandy soil foundations is stated. The influence of districts and compression process on sandy soil foundations are analyzed under construction complimentary load. A further prediction method on sandy soil liquefaction is given in complimentary press field. It is pointed that the property of sandy soil liquefaction around foundation and in transition press field Ⅱ is weaken, which is a vital precautionary field for liquefaction treatment.
