Background

In surveying and mapping, construction and other applications, various instruments are generally adopted to measure angles, distances and elevations, and the self-weight stress of the soil body self-gravity exists in the foundation before buildings and geotechnical buildings are built. The load of the building and the geotechnical building is transmitted to the foundation through the bottom surface of the foundation or the embankment, so that the original stress state of the natural soil layer is changed, and vertical, lateral and shearing deformation is generated in the foundation under the action of an additional three-dimensional stress component, so that vertical and lateral displacement of each point is caused. The vertical deformation of the foundation surface is called foundation settlement, or foundation settlement, which is more or less always uneven in the foundation or embankment parts due to differences in building loads and uneven foundations, causing correspondingly additional stresses and deformations in the superstructure or pavement structure. The uneven settlement of the foundation exceeds a certain limit, which can cause the cracking, the deflection and the even damage of the building, such as the cracking of brick walls, the clamping or the sliding of crane wheels, the inclination of high-rise structures, the deflection of machine rotating shafts, the fracture of connecting pipelines with the building, the deviation of bridges from abutments, beam surfaces or road surfaces, and the like.
