摘　　要：通过分析湛江组薄层状黏性土的物理力学性质,比较标准贯入试验、土工试验、轻型动力触探试验等不同测试手段所得承载力特征值的差异,并分析其产生差异的原因,进而阐述在岩土工程勘察和地基基础施工时需要注意的问题,避免因人为因素影响而误判湛江组薄层状黏性土的承载力特征值。Based on the analysis of the physical and mechanical properties of the thin layered cohesive soil in the Zhanjiang formation, the differences of the characteristic values of the bearing capacity obtained from the standard penetration test, geotechnical test and light dynamic penetration test are compared. The paper also analyzes the reasons for the differences, and then expounds the problems that should be paid attention to in geotechnical engineering investigation and foundation construction, so as to avoid misjudging the bearing capacity characteristic value of the thin layer cohesive soil of the Zhanjiang formation due to the influence of human factors.
