Research on the Pore Characteristics of Dredger Fill By Preloading
Lecture Notes in Civil Engineering, 2023 AbstractThis study investigated the characteristics of dredger fill after preloading at the DaLian. Granulometric composition test and X-ray diffraction were employed to determine the composition of dredger fill. Mercury intrusion porosimetry was combined to determine the related features of the pore.

Study on Consolidation Test for Fresh Soft Dredger Fill
Applied Mechanics and Materials, 2014The consolidation test was performed to samples of fresh soft dredger fill with heights of 2cm, 3cm and 4cm with full-automatic pneumatic consolidometer. The results show that: the soil sample deforms greatly during the consolidation with significant decrease in water content and small consolidation coefficient.
