采用强夯法处理沿海地区的砾质粘土回填地基，其承载力的评价是一尚待解决的问题。本文结合工程实例，具体介绍了沿海地区茂名乙烯工程砾质粘土回填地基，经强夯加固处理后的载荷试验、标准贯入试验结果。提出了ｆ＿ｋ—Ｎ＿（６３．５）的关系曲线，为该工程采用标贯试验进行地基承载力检测提供依据。 The evaluation of bearing capacity of the gravel clay backfill foundation in the coastal area by using the dynamic compaction method is a problem that remains to be solved. In this article, combined with engineering examples, the load test and standard penetration test results of the backfill foundation of Maoming Ethylene Engineering Gravel Clay in coastal area were introduced in detail. The relationship curve of f_k-N_(63.5) is proposed, which provides the basis for the project to use the standard penetration test to test the bearing capacity of the foundation.
