Abstract

During long-term operation, buildings and structures for various reasons receive various defects and damage in the form of precipitation and subsidence of the soil base, rolls of buildings and structures, deformations and displacements of the elements of the bearing base, which are recorded by geodetic methods. Traditionally, while examining buildings and structures, geodetic methods are based on optical instruments (theodolites, levels, total stations) and grades, which are installed on the elements of controlled buildings and structures are used. The indicated optical methods, on the one hand, give high accuracy in registering deformations of the foundations and structures in comparison with other known methods, and on the other hand, the most famous methods have a number of disadvantages. This article has collected and refined information about one of the most effective geodetic method for assessing the deformation of the structures
