| 摘 要： | 结合某核电站地基加固工程，在强夯试验期间运用多种原位测试方法，对不同能级强夯下防渗墙的振动强度以及防渗墙的安全状态进行了实时监控。基于试验结果，分析了各能级强夯振动对邻近的海工防渗墙抗渗性能和各段间搭接面完整性的影响；结合现场条件，提出了防渗墙的振动速度控制标准，并用于指导正式强夯期间的施工。长期监测结果表明，采用的监控方案合理可行、原位测试方法准确可靠，为类似工程的强夯振动安全性评价提供了重要参考。

| Abstract: | Combining the dynamic consolidation of a nuclear power plant foundation,varieties of in-situ tests are used to monitor the vibration intensity and safety of cutoff wall under dynamic compaction.Through experimental research,dynamic compaction parameters which ensure the cutoff wall safety and the dynamic compaction effect are analyzed;the controlling standard for long-term dynamic compaction is given.The long-term monitoring results show that the adopted monitoring scheme is reliable and efficient so as to provide a very important reference for the similar projects′ safety assessment. |
