Physical and Chemical Characteristics of High Clay Content Dredger Fill in Different Regions

The use of high clay content dredger fill is a popular way to reclaim and create new land for development in coastal areas. In this paper, the dredger fill samples were obtained from 7 locations on the Bohai Sea coast in China. The soils were tested for Granulometric composition, physical composition, chemical composition, and Atterberg Limits. These results are reported. The principle finding shows that the chemical composition of the pore fluids, such as namely problems of drainage and consolidation, has influence on the geotechnical properties of different soils. This work provides the basis for further research on the drainage and consolidation properties of high clay content dredger fill.
