In traditional waterway engineering,the main method of foundation treatment in dredger filling area is vacuum preloading or surcharge preloading,and the main method of foundation treatment in non-dredger filling area is dynamic compaction.Taking the second phase of the container terminal project of the second harbor basin of Jinzhou Port as an example,we divide the site area according to different geological conditions,and carry out the comprehensive treatment by choosing different processes.According to the treatment results of surcharge preloading,dynamic compaction (dynamic compaction replacement) and vibroflotation,we verify the applicable conditions of three soft foundation treatment technologies,which can provide reference for similar engineering construction.
