Abstract
Hydraulic filling is used for land reclamation work and/or to increase the ground level of low-lying
areas. Changes in gradation properties of the hydraulic fill is to be expected during hydraulic filling process which comprises dredging, transportation, deposition, and compaction. These changes in gradation can influence the hydraulic conductivity (permeability coefficient) of the resulting hydraulic fill mass. This hydraulic conductivity is further exacerbated by potential ponding of the transient remnant sea water within the constructed fill mass and its extent in relation to location of points of discharge and the groundwater regime of the area. This paper examines the effect of change in gradation on the hydraulic fill mass coefficient of permeability, using the grading entropy framework to investigate changes in the coefficient of permeability of the hydraulic fill mass. The paper also examines the possibility of applying the gradation entropy framework to assess the liquefaction potential of sand fill mixtures ‘after deposition’ and the in-situ granular foundation strata due to seismic events.
