Real-Time Behaviour of Dredged Slurry Treated by Air-Booster Vacuum Consolidation
Applied Sciences (Switzerland), 2023 The air-booster vacuum preloading method has been applied to slurry ground improvement. It is based on the conventional vacuum preloading method but with an additional injection of pressurised air into the soil via pre-installed conductors.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.The vacuum preloading combined with prefabricated horizontal drain (PHD) is an effective foundation treatment method for high‐water‐content dredged slurry. As the key design parameter of PHD vacuum preloading technology, the vertical spacing of PHD directly affects dredged slurry consolidation efficiency. However, its optimal value has not been clearly

Review and Integrated Framework for Deep-Sea Mineral Resources, Ecological Influence, and Future Development. [PDF]
Int J MicrobiolAs global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

The effect of initial water content on the consolidation of dredged slurry under vacuum preloading
Rock and Soil Mechanics, 2021 In the process of treating the dredged slurry under vacuum preloading combined with the prefabricated vertical drains (PVDs), a dense “soil column” with low permeability will be formed around the PVD, which results in a poor drainage condition and an ...
