摘　　要：随着沿海港口建设事业的发展,为疏浚航道和扩建泊位,需要挖掘大量的海底淤泥,与此同时,一些港口还存在陆域不足的现状,如能将疏浚出来的淤泥用来吹填造陆,则是一举两得、变废为利的好办法。吹填的淤泥固结性能差,吹填以后自然沉积固结要经过很长时间才能完成,待表面形成硬壳后方可进行加固处理。通过试验,研究泥浆在沉积固结过程中一些参数的变化,得到了相应的结论。With the rapid development of coastal port dredging and berth expansion, to dredge up a lot of construction, it is required, for the purpose of channel silt from sea bed, at the same time, some harbors are lack of land area, therefore, land reclamation with the silt dredged may be a good method to kill the two birds. As the consolidation property of the dredged silt is poor, the self-weight sedimentation and consolidation after dredging will take a long time, and reinforcement may be carried out only after a hard shell is formed on the surface. Through test, the change of some parameters of the mud during the sedimentation and consolidation was studied, with the results concluded.
