[0002] The ground foundation refers to the soil or rock mass supporting the foundation of the building. The soil layer serving as the building ground foundation is classified into rock, gravel soil, sand, silt, clay and artificial fill. The ground foundation is of two types, namely, natural ground foundation and artificial ground foundation (composite ground foundation). The natural ground foundation is the natural soil layer without human reinforcement, and the artificial ground foundation needs to be reinforced and treated by human beings. Commonly, there are stone chip cushion, sand cushion, mixed lime-soil backfill and ramming, etc.

[0003] The ground foundation settlement refers to the subsidence of the ground foundation surface caused by the compaction of the ground soil layer under the action of additional stress.
