| Bulking change between sediments and dredged soils occurs when dredged soils are fully disturbed by dredging process and settled down to stabilized conditions in the basin. Bulking of dredged soils are affected by chemical injection, coagulant and flocculant, to speed up settling process of the suspended solids. In this paper, bulking changes of dredged soils are investigated by experimental works regarding injection effects of the coagulant and flocculant. Dredged sediments were sampled in the lagoon located at the East Coast, and the bulking change of dredged soils is quantitatively analysed by changing the clay content and the amount of the coagulant and flocculant. The optimal amounts of the coagulant and flocculant are determined based on minimal bulking change due to coagulant and flocculant injection. From the experimental results, the bulking of dredged soils increased 1.69 times on the average and the bulking change rate slightly increased as clay content increasea due to injection of the coagulant and flocculant. |
