| 摘 要： | 爆夯是一种利用炸药爆炸法夯实基础的新技术，近年来被广泛地应用于码头建设。笔者介绍了广西钦州港二期码头抛石基床的爆夯设计和实施。结果表明，基床爆夯达到了预期效果，水下爆夯的平均沉降率为12.7%。同时，爆夯过程中，一期码头的振动值小于安全阈值，保证了一期码头的安全，为类似工程提供了借鉴。

| Abstract: | Underwater explosive ramming is a widely used method to strengthen foundations for docks. The design and implementation of underwater explosive ramming for the second phase dock of Qingzhou Harbor in Guangxi Region, are introduced. It is indicated that the average subsidence of the dock is about 12.7%; and the strengthening effect is quite good. It is also reported that the vibration induced from the explosive ramming for the first phase dock is less than the threshold value, which ensure the safety of the first phase dock. The work presented can be a good reference for similar engineerings. |
