Conclusions It is necessary to note a number of features of the measurement methods used for the first time by Ukrgidroproekt for determining the deformations of hydraulic structures, which in our opinion can be used on other objects and under other working conditions. 1. The use of reverse plumb lines as fundamental geodetic points. 2. Determination of displacements, mainly of the structures of navigation locks, by the method of high-precision linear measurements. 3. Use of special devices for tensioning Invar wires, which eliminated the use of the cumbersome station equipment from the BP-2 kit (straining trestles). 4. Markers with automatic centering of instruments having designs compatible with the site of embedment and soil conditions were used on all fundamental and survey check markers. 5. The manufacture (by Ukrgidroproekt) and use of the string base-meter permits prompt and quick determination of the relative displacements of individual structures. The technique of special survey measurements made it possible to solve the stated problem — to determine the absolute horizontal and vertical displacements of hydraulic structures of the Dnepr cascade of hydrostations with an accuracy of 1–3 mm.
