摘　　要：对合肥地区天然基槽中可塑状黏性土同时进行静力触探试验和轻型动力触探试验,按照同一个行业检测规范,2种试验值估算的承载力特征值相差较大;通过拟合静力触探值与轻型动力触探数值的对应关系,利用安徽省地方标准中静力触探和承载力特征值的推荐公式,给出在合肥地区可塑状黏性土天然地基验槽中轻型动力触探数值与承载力特征值对应的关系表格,用于指导实践。Static penetration test and light dynamic penetration test are conducted simultaneously on the plastic cohesive soil in the natural foundation trench in Hefei area.According to the same industry testing standards,the estimated bearing capacity characteristic values of the two test values differ significantly.By fitting the correspondence between static penetration test values and light dynamic penetration test values,and using the recommended formulas for static penetration test and bearing capacity characteristic values in local standards in Anhui Province,a table for the correspondence between light dynamic penetration test values and bearing capacity characteristic values in plastic cohesive soil natural foundation testing in Hefei area is proposed to guide practice.

关 键 词：轻型动力触探 承载力特征值 天然地基验槽
