The content of deformation monitoring shall be determined according to the nature of the deformed body and the condition of the foundation. Deformation monitoring mainly involves the acquisition of deformation information, the analysis, interpretation and deformation prediction of deformation information. The main deformation monitoring methods include ground conventional measurement technology, ground photogrammetry technology, special and dedicated measurement methods, etc. Among them, the fully automatic tracking total station provides a good technical means for the automatic detection of local engineering deformation, and can carry out unattended, all-weather, all-round automatic detection within a certain range.
