Influence of dredger fill self-consolidation on development of negative skin friction of piles
Arabian Journal of Geosciences, 2020With the rapid development of land reclamation, a great amount of buildings are constructed on degree fill. Negative skin friction (NSF) caused by the self-consolidation of dredger fill has a significant influence on the stability of construction. Therefore, centrifuge model tests were conducted to investigate the influence of dredger fills thickness ...

Experiment Study of Dredger Fill Using Different Consolidation Methods
Advanced Materials Research, 2014At present, there are many methods of the dredger fill foundation treatment, in which the most widely used application of vacuum preloading method. The dredger fill for test was taken from the Tianjin Binhai new area center fishing port area, separately carried on the self-weight consolidation and vacuum preloading consolidation.

Drainage Conditions and Pore Water Pressure's Change of Dredger Fill
Civil Engineering and Urban Planning 2012, 2012Many factors affected dredger fill’s consolidation. Dissipation of pore water pressure reflects the hydraulic fill’s consolidation process from another angle. In this paper, hydraulic fill with the high clay content as study object. Indoor simulation experiments carried out under different drainage conditions: the same drawdown of different drainage ...

Deformation and failure mechanism of rapid stabilization for dredger fill in road engineering
Arabian Journal of Geosciences, 2020Foundation deformation and failure of a finite length double-layered foundation by rapid stabilization was studied with regard to dredger fill in road engineering. Deformation and bearing capacity theories were proposed based on the discontinuous deformation and the lower strength.

Test on consolidation of dredger fill by cube grid of plastic drain board preinstalled
Engineering Geology, 2012Abstract The test on consolidation of dredger fill was conducted by preinstalled cube grid in the dredger fill. The settlement of consolidation and dissipation of excess pore water pressure were analyzed. The test results showed that the development of settlement of consolidation includes slow rise stage, accelerated rise stage and sharp decelerated ...

Research on Surface-Layer Improvement Technology for Dredger Fill by Vacuum Preloading
Applied Mechanics and Materials, 2012The surface-layers have very high water content and low bearing capacity, so far to be the very soft clay foundation, which come from the reclaimed land in project of reclamation. It is difficult to improve the very soft clay foundation by traditional vacuum preloading.

Laboratory Test Study on Rapid Chemical Deposition of Fresh Dredger Fill
Advanced Materials Research, 2013After hydraulic reclamation of the dredger fill, as the deposition of surface sludge requires a relatively long time, the consolidation treatment cannot be immediately performed until the sludge-water separation is completed and the separated water is drained. The laboratory test makes a research on the effects of chemical agents and drainage condition
