摘　　要：文中研究了沿海工程软土地基加固工作中强夯法的施工技术,并分析施工过程中影响强夯法作业的主要因素与施工难点问题。通过对福建兴化湾陆域软土地基的2个试夯区进行强夯加固,分别采用静载荷试验、动力触探试验、瞬态瑞雷面波试验三种不同的测试技术并结合工程实践进行加固效果比较,试验检测结果表明达到了软土地基加固处理要求。最终提出适合福建兴化湾陆域软土地基强夯加固施工技术方案,得出强夯施工技术参数。This article studies the construction technology of dynamic compaction method in the reinforcement of soft soil foundation in coastal engineering,and analyzes the main factors and construction difficulties that affect the operation of dynamic compaction method during the construction process.By conducting dynamic compaction reinforcement on two test areas of soft soil foundation in Fujian Xinghuawan,three different testing techniques including static load test,dynamic penetration test,and transient rayleigh wave test were used in combination with engineering practice to compare the reinforcement effect.The test results showed that the requirements for soft soil foundation reinforcement treatment were met.Finally,a construction technology scheme suitable for dynamic compaction reinforcement of soft soil foundation in Fujian Xinghuawan was proposed,and the technical parameters of dynamic compaction construction were obtained.
