To investigate the settlement heave characteristics of excavated materials from the basin,we design the large-scale in-situ flooded embankment test.The model with dimensions 20 m×20 m×1 m includes two different parts of fine contents (passing through 0.063 mm):one part comprising fine contents less than 20%,the other part of 35%～45%.Based on the model test result,we conclude that the swelling process can be divided into three phases,i.e.the initial rapid swelling phase,the slowly increasing phase and the stable phase.The rate of swelling varies with the flooding time in such a pattern:maximum,low,gentle.The rate for fine contents less than 20% with a higher initiative rate is faster than the fine content 35%～45% in the first phase,and the excavated fill is non-sensitive to fine contents since the final heave of different fine contents are both 9.0 mm.The flooded embankment test may serve as reference for the design and engineering application of excavated fills in new Doha port.
