Drainage Conditions and Pore Water Pressure's Change of Dredger Fill
Many 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 rates, different drawdown rate of the same drainage. Comparison time of soil initiation drainage, the rate of drainage, and the dissipation of pore water pressure in the different drainage conditions. When the larger drawdown rapid drainage, found the soil has been reinforced around vertical drainage pipe first, pore water pressure changes so little when the soil away from the vertical body. Comparing speaking, the cohesive soil would be easier to consolidation in small drawdown and slow drainage process. Select the appropriate drawdown and drainage rate could be achieved better results of cohesive soil consolidation.
