Abstract: In order to study the permeability characteristics of solidified dredged mud, we carry out indoor experiment with variable water head. During the experiment, the effects of curing condition, blending ratio of curing agent and curing age are taken into consideration. The results show that under given curing condition, permeability coefficient decreases with the increase of blending ratio of curing agent and curing age. Furthermore, the range of appropriate blending ratio of curing agent for permeability prevention in actual projects varies from 6% to 8%, and appropriate blending ratio of curing agent with 10% of fly ash is 5%. The test results offer reference for engineering design and construction in similar projects.

Key words: solidified dredged mud, permeability test, blending ratio of curing agent, permeability coefficient, permeability characteristics
