Abstract: The uniformity of the traditional foundation was evaluated by the uneven coefficient，but the method cannot reflect the specific distribution characteristics of the site parameters.According to this weakness，the comprehensive evaluation method combining the uneven coefficient and the variation coefficient was put forward on the basis of the traditional method.Combined with the dynamic compaction foundation treatment project at the first stage of Ganyu port area in Lianyungang，a series of in-situ testes were carried out to discuss the performance and reliability of the proposed method in the foundation uniformity evaluation.The results show that the proposed method can not only synthetically evaluate the uniformity of the foundation，but also can systematically evaluate the foundation from the plane and the depth range.

Key words: geotechnical engineering, foundation uniformity, evaluation method, uneven coefficient, variation coefficient

摘要： 传统地基均匀性采用不均匀系数评价，但该方法不能反映场地参数的具体分布特征。针对该不足，在传统方法基础上，经过多次比对，提出了不均 匀系数和变异系数相结合的综合评价方法。并结合连云港赣榆港区一期强夯地基处理工程，开展多种现场原位试验，明确所提出新方法在地基均匀性评价 中的应用效果和可靠性。结果表明：所提出的方法不仅可以综合评价地基均匀性，还可以从平面和深度范围对地基进行系统评价。
