在一些工程建设中.如路基、堤坝的填筑和建筑场地的回填等。土体常作为建筑材料。±体由于经过挖掘、搬运和填筑.原有的结构和状态发生改变,如不经过人工压实.孔隙比往往较大,而且压缩性较高、抗剪强度低,难以满足工程的需要。为了减少填土的工后沉降量,提高强度,工程中必须按照一定的标准,通过碾压、夯实或振动等方法对其进行压实。土的压实效果除了和压实方法有关外,还和土的种类、级配、压实功能和含水率等密切相关。

沉积物的分选和压实作用影响渗透率和孔隙度。
Sediment sorting and compaction influence permeability and porosity.
当水被抽出来时,剩余的空间被上层的泥土填满压实。
As the water is pumped out, the vacant space left is compacted by the weight of the earth above.
沉积物分选越差或压实越紧,其孔隙度和渗透率就越低。
The more poorly sorted or the more tightly compacted a sediment is, the lower its porosity and permeability.
