To improve the quality of construction and increase the durability of engineering structures under construction, complex geodetic works should be performed, including geodetic observations of deformations of structures. These observations are carried out during the construction of buildings and structures and their operation, mainly before the period of deformation stabilization. In this regard, a reliable statistical definition of deformations close to the limit is necessary, based on the data of geodetic observations. The research helps to improve the definition of deformations of structures using the Fischer’s F-test and the Foster-Stuart test, based on analysis of the measurements of horizontal and vertical monitoring of industrial structures. According to the results, the magnitude of the subsidence plays a more significant role from than its absolute value, thus the value of the deformation intensity is of primary importance in justifying observation periodicity.
For the vertical deformation monitoring of the construction of the Family Park shopping centre facility in Samarkand, Uzbekistan, a monitoring network has been established including 12 benchmarks installed on the wall of the building. Altogether 8 of control surveys were observed during the time span of the construction, and based on them, an estimation for future subsidence has been provided by extrapolating of best-fitting exponential curve. It was found that in all test points the relevant subsidence has been ceased. A further test has been provided to estimate the tilting of the building. The value of the tilting was estimated to be 0.06‰, which was also found to be unidirectional, so no deformation of the structure can be expected due to it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
