摘　　要：该文根据《建筑抗震设计规范》等国家技术标准的规定,结合江苏地区电力工程的勘察经验以及国内外最新的理论研究成果,对饱和砂性土液化判别与计算中存在的几个问题进行分析,针对上覆非液化土层厚度的确定、粘性土互层与夹层的考虑、以及6度区对沉陷敏感的乙类建筑的规定等问题作了一些探讨,旨在为砂性土的液化计算积累一些有益的经验。Based on the regulation of some state technical criteria such as Code for Seismic Design of Buildings, and combining with the geotechnical investigation experiences of electric power project in Jiangsu region and the latest theoretical study abroad and domestic, the paper analyzes several problems in distinguishing and calculating liquefaction of saturated sandy soil, then discusses some objective instances just as the determination of the overburden non-liquefied soil thickness, the consideration of interbed and interlayer clay, and the stipulation of sensitive category Ⅱ buildings to settlement in areas of seismic intensity 6, it aims to accumulate some useful experiences for the liquefaction calculation of sandy soil.
