Investigating the accuracy of the excess determination at the levelling station basing on the results of multiple measurements
Abstrak
The author considers the accuracy of multiple measuring the excess obtained during the work on geodesic support of the definition of certain road sections surface wear-and-tear degree in the Altai region. Basing on these results in nine cycles for seven federal highways’ sections, the accuracy of determining the excess between the reference points and the roadway points was evaluated. It is noted that at performing the work, the standard deviation measuring excess at the station can serve as a criterion for accuracy. Various options of its calculation are considered, depending on which measurements are taken in joint processing. The analysis of the root-mean-square errors obtained as a result of parsing different variants is performed. It is also noted that the data gathered during the research should be considered at engineering-technical leveling as well as in the process of measuring the values of seasonal road base points’ changes in automobile road sections which are surveyed to define the deterioration rate of the road pavement.
