摘　　要：强夯法是在重锤夯实法基础上发展起来的,具有工期短、费用低、效果显著等优点。由于地质复杂,在施工前必须通过现场试验,确定其适用性和处理效果。通过黄河尼那左岸副坝工程实例,分析了强夯法相关试验的结果,确定相关技术参数,实践证明强夯法是处理湿陷性黄土地基较经济合理的方法。The dynamic compaction is based on hammer compaction method foundation,which has the advangtages of shorter construction period,low cost,significantly and effect,etc.Because the geological is complex,in-site test should be done before construction to determine the applicability and treatment effect.Based on the left bank assistant dam of Yellow River project in Nina examples,the dynamic compaction method relevant test results are analyzed to determine the related technical parameters.It proves that dynamic compaction is reasonable and an economic method to deal with collapsible loess foundation.
