Based on in situ investigation and experiments,the paper introduces the distribution characteristics and engineering properties of the dredger fill in Liaodong gulf to supplement theoretic research of dredger fill,and their properties are various owing to effects of many factors,such as the different source of dredger fill,consolidated time and site conditions.To make further analysis,two typical fields (A and B regions)are selected to research engineering properties and micro structure through a series of experiments,such as compaction and consolidation,mercury penetration and scanning electron microscopy (SEM);then the rule of consolidation is obtained combining with the change of depth.Results show that A and B have different degrees of consolidation with different depths,however,A has the same consolidation phase and the consolidation phase of B is different.
