| Abstract: | Based on the in-depth investigation of geological conditions in hydraulic fill soil foundation of Qinzhou Bonded Port,the article elaborated the main technical issues of pipe-line excavation and backfill,and through the comparative analysis on the advantages and disadvantages of various current pipe-duct burying programs,it proposed new ideas of comprehensive treatment using the steel-sheet pile＋ vibration watertight method regarding the excavation and pipe burying in the segments without foundation treatment,thereby pro-viding the technical reference for the selection of pipeline excavation and burying programs in hydraulic fill soil areas or high water-level soft-soil sand foundation. |
