| 摘 要： | 为了探讨在软土区山皮土与细砂2种不同回填土土质条件下的强夯加固效果，在同一滨海区开展了2种回填土土质条件下的现场强夯对比试验。并对现场不同试验区强夯前后标准贯入试验（SPT）与浅层平板载荷试验结果进行分析与对比研究。根据所得出的结论，提出了进一步提高强夯后地基处理效果的建议。

| Abstract: | In order to investigate the dynamic compaction effects under 2 different backfills of hill-skill soil and fine sand in soft ground, the field comparative tests were made in the same littoral area. The results of standard penetration test (SPT) before and after dynamic compaction and the shallow plate loading test were analyzed; and the comparative tests were also conducted. Based on the conclusion, the suggestions are put forward to further improve the foundation treatment effects after dynamic compaction. |
