The construction of an engineering facility generally needs three stages of investigation, design and construction, and subjects such as engineering geological investigation, hydrogeological investigation, engineering measurement, soil mechanics, engineering design, building materials, building equipment, engineering machinery, building economy and the like, knowledge in the fields of construction technology, construction organization and the like, and technologies such as electronic computer and mechanical test and the like need to be applied.
Among them, civil engineering is a subject with strong practicality. In the early days, civil engineering was developed through engineering practices, summarizing successful experience, and especially absorbing failed trainings. For civil engineering, the measurement of the geographic environment is an indispensable practical basis and theoretical basis, and mainly, the objective conditions of most fields are too complicated to faithfully carry out indoor experiments or field tests and theoretical analysis. For example, the stress and deformation states of foundation foundations, tunnels and underground works and the changes of the stress and deformation states along with time, so that the measurement in the early stage, construction and acceptance is very critical according to the needs of the works.
Common measuring instruments comprise a level, a theodolite, a total station, a concrete rebound instrument, a crack width gauge, a floor thickness gauge and the like, and the instruments are high-precision electronic instruments and have extremely high requirements on stability and fine angle adjustment. For example, a Total Station, i.e., a Total Station type Electronic distance meter (Electronic Total Station), is a high-tech measuring instrument integrating light collection, mechanical measurement and electrical measurement, and is a surveying instrument system integrating horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite changes the optical scale into the photoelectric scanning scale, and replaces manual optical micrometer reading with automatic recording and displaying reading, so that the angle measurement operation is simplified, and the generation of reading errors can be avoided. The total station is called because the instrument can be arranged once to complete all measurement work on the station. The method is widely applied to the field of precision engineering measurement or deformation monitoring of overground large-scale buildings, underground tunnel construction and the like.
Although the instruments are advanced and accurate, if the supporting structure is unstable and not easy to adjust, the accuracy of the measured data can be directly influenced.
