在工程建设中,经常使用人工压实的土作为路堤、土堤等构筑物的材料或建筑物的地基,若使用原状结构被破坏的土作为建筑物的材料或地基时,土的强度低,压缩性大,沉降不均匀,有的会发生湿陷或者崩解等现象。用击实的办法能使土在外力作用下,短期内得到新的结构强度,降低土的压缩性和渗透性,改善土的工程性质。压实的效果与工地压实条件(压实功能)和土的性质有关,相同的压实功能对不同状态的土会得出不同的效果。所以用土做建筑材料时,需
In engineering construction, artificial compacted soil is often used as the foundation of embankment, embankment and other structures or foundation of buildings. If the original structurally damaged soil is used as the building material or foundation, the strength of the soil is low and the compression Sex, settlement uneven, and some may collapse or collapse and so on. Compaction method can make the soil under the action of external forces in the short term to get a new structural strength, reduce soil compressibility and permeability, improve the engineering properties of soil. The compaction effect is related to the site compaction conditions (compaction function) and the nature of the soil. The same compaction function will produce different effects on the soil in different states. Therefore, the use of soil as building materials, required
