| 摘 要： | 强夯法是地基处理的一种常用方法，而强夯施工振动往往是制约强夯法应用的关键。结合沿海某港口工程地基处理中的强夯振动工程实例，介绍了强夯法地基处理引起的振动在土中纵、横向的传播和衰减情况。根据实测结果，分析了强夯振动对周围环境的影响，并建议了振动的防治措施。此外，还针对深度方向上的处理效果提出了分带方案。

| Abstract: | Dynamic compaction is one of methods for groundwork treatment. But the vibration during dynamic compaction often becomes a problem that restricts the application of dynamic compaction. Combined with dynamic compaction vibration of a harbor engineering, the law of vibration propagation and attenuation is presented. Based on the monitoring data, the influence of the vibration on environment is analyzed and measures for preventing dynamic compaction vibration are put forward. Scheme was provided according to effect of treatment on depth. |

| Keywords: | dynamic compaction vibration effect attenuation law environmental influence |
