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...
