Analytical solution on vacuum consolidation of dredged slurry considering clogging effects

Geotextiles and Geomembranes, 2021
Abstract This paper aims to establish an analytical model on vacuum consolidation of dredged slurry treated by PVD with special considerations on the clogging effects. A series of laboratory tests have been conducted to characterize the temporal/spatial variations of the clogging zone and the vacuum pressure in soil.

Vacuum preloading and electro-osmosis consolidation of dredged slurry pre-treated with flocculants

Engineering Geology, 2018
Abstract To improve the consolidation of dredged slurry, a combined method of vacuum preloading and electro-osmosis consolidation was applied to a dredged slurry pre-treated with flocculants. In this study, the optimal mixing ratio of two conventional inorganic flocculants was determined by conducting a settling column test.

Uniaxial compression test of cement-solidified dredged slurry columns encased with geogrid

Geosynthetics International
This study investigated the performance of unreinforced and geogrid-encased cement-stabilized dredged slurry columns by uniaxial compression tests to simulate the extreme case where the surrounding soil offers no confinement. The objective was to understand the strength characteristics and visualize the deformation damage patterns of the columns with ...

Effect of a vacuum gradient on the consolidation of dredged slurry by vacuum preloading

Canadian Geotechnical Journal, 2021
In this paper, a large-scale indoor model test was carried out to reinforce dredged slurry by vacuum preloading, and the effect of the vacuum gradient on the reinforcement effect was studied. The vacuum pressure, volume of extracted water, average ground settlement, and excess pore-water pressure were monitored during the test.

Consolidation Characteristics of Dredging Slurries

Journal of the Waterways, Harbors and Coastal Engineering Division, 1973
With the population growth and the industrial development of a given region, the sediments dredged from the harbors and channels have become increasingly polluted. As an alternative to open water disposal, many of these dredgings are deposited behind dikes in areas near harbors; although more expensive than open water disposal, this latter scheme has ...
