MODELING AND MATHEMATICAL PROCESSING OF GEODETIC LEVELING NETWORK WHILE MONITORING SETTLEMENT OF UNIQUE ENGINEERING STRUCTURES

Abstract

The paper shows that reliability and trust of geodetic structure monitoring are related with new principles of leveling network construction, their testing and mathematical processing. Two indices, point density and errors in their altitude location, have been considered recently as the main characteristics of geodetic construction quality used for geodetic monitoring of engineering object settlements.As it is an evitable distortion of the measuring data in the process of its accumulation and processing due to influence of additional factors (rough and systematic measurement errors, original data errors and so on), nowadays while evaluating the quality of geodetic constructions one more important characteristic is to be taken into account that is reliability of the geodetic construction.The majority of standard geodetic construction schemes do not have a sufficient reliability rate for definitive determination of construction settlements in any measuring cycle. Due to this very reason a problem concerning higher reliability of geodetic constructions and efficiency of their mathematical processing and, in consequence, provision of more accurate determination of engineering object settlements is considered as an actual one and it finds its solution in the paper.
