Abstract
The article considers methods of misalignment determination of constructions and equipment, and analyses methods based on the spatial section line location. It is noted that in certain conditions the use of total stations and GNSS-receivers allows to perform a section line the measurements with necessary accuracy. To carry out measurements on the overall discharge section line program the improved method is suggested. The advantage of the suggested method is that if there is no opportunity for compulsory centering of a total station on the survey control points of the section line, it suggests using an extra survey control point of dam site to increase the measurement accuracy. The extra survey control point is settled in the site with high accuracy with the help of centering device. The measurements were performed by the suggested method and the results were analyzed. It was stated that the considered method increases the accuracy of misalignment determination of the control points on the overall discharge section line program.
