Adamenko O. Methods of calculating accuracy of geodetic operations during bridge construction by simulating strain condition

The object is accuracy of geodetic operations in the process of the bridge building. The methods - the concepts and specifications of the structural theory, finite-element method, theories of dimension chains, and concept of the least and equal effects of measurement uncertainty are used in the research. The feature of novelty - the preliminary calculation model and values simulation of initial displacement of the bridge substructures have been worked out, the method of accuracy calculation of geodetic operations in the process of the bridge building has been developed, the method of accuracy calculation of geodetic operations in the process of the bridge building with the help of the special software for calculation building constructions and the method of analytical account of building substructures displacement during setting it into the permanent position were offered. The results - obtained results contain the new technical approach to the rating of operations accuracy and technologies of implementation of geodetic measurements during bridge building, namely: the method of investigation of accuracy of geodetic operations improves objectivity and relevancy of the rating of geodetic operations accuracy and raises reliability of the bridge exploitation; the method of analytical account of building substructures displacement allows to facilitate the task of keeping the geometry of building structures. The field is geodesy and land boundary survey.
