Dredger fill making roads is an effective way to solve the land shortage in coastal areas�� In order to quicken drainage consolidition and shorten the construction period of dredger fill��taken the dredger fill in coast region of Tianjing as studied object��the basic properties and subsidence characteristics of dredger fill in Tianjin were studied by water subsidence and laboratory tests without external force self-weight consolidation�� The consolidation and subsidence characteristics of dredger fill in Tianjin has been obtained through the quantitative analysis of the consolidation degree and velocity��and its evaluation�� The results showed that the graduated compression constant amplitude waterhead inhabited the formation of low permeability soil to some extent�� The consolidation degree closed to 100% when the waterhead was 45 cm�� The consolidation degree was better with the closer distence from drain�� The permeability decreased and the soil tended to consolidation when the accumulation load increased��
