摘　　要：以山东龙口某地基处理项目为研究背景,对标准贯入试验中贯入击数、液化指数等相关参数进行分析,综合判定地基土是否存在砂土液化现象。研究结果表明,通过对现场地基处理场地进行标贯试验,各试验点均无砂土液化现象;标准贯入试验作为传统且成熟的原位测试技术,避免了室内试验中土壤扰动情况的发生,在判定砂土液化方面具有较大优势。Based on the research background of a foundation treatment project in Longkou,Shandong Province,the relevant parameters such as the number of penetration blows and liquefaction index in the standard penetration test are analyzed to comprehensively determine whether there is sand liquefaction in the foundation soil.The research results show that there is no sand liquefaction phenomenon at each test point through the standard penetration test on the site foundation treatment site;Standard penetration test,as a traditional and mature in-situ testing technology,avoids soil disturbance in the laboratory test and has great advantages in determining sand liquefaction.
