所谓吹填造陆就是将疏浚航道挖出的淤泥强力吹填到围堤中，经过沉积固结处理，形成大面积陆域，供港口建设使用。其优点是可以大规模处理淤泥，缺点是由于淤泥天然含水率高，几乎处于流变状态，排水固结时间长，
The so-called hydraulic reclamation is to forcibly dredge and fill the silt excavated from the dredged channel into the embankment and form a large land area for port construction after sedimentation and consolidation. Its advantage is that it can treat sludge on a large scale. Its disadvantage is that the sludge has high natural moisture content, almost in rheological state and long drainage consolidation time,
所以需要花很大力气进行地基处理，处理周期长，花费的费用高，而且等处理后地基达到一定承载力后才可以使用，一般只用于近海或者近港口地区的淤泥处理。
Therefore, great efforts need to be made to carry out foundation treatment. The treatment cycle is long and the cost is high. Moreover, it can be used only after the treated foundation reaches a certain bearing capacity. Generally, it is only used for sludge treatment in offshore or near port areas.
