Model Test Study on Dredge Slurry Vacuum Preloading
DEStech Transactions on Engineering and Technology Research, 2018 Dredge materials with the water content more than 80% have been used for land reclamation in Tianjin, China. The dredge is transferred by pipeline to the reclamation place and then strengthened with the vacuum preloading technique. It has been found that with the thickness of the filled dredge layer becomes larger and larger, the quality of soil ...
