【 摘 要 】

Measurements of vertical displacements using geodetic methods consist in the determination of changes in the location of reference points on the object or of its whole components. Such measurements require a high accuracy which can be ensured by the application of appropriate measuring instruments and measurement technologies. Modern measurement methods enable us to undertake tasks which traditional methods could not handle, and the required precision is guaranteed. This article describes an analysis of measurements of vertical displacements taken by means of a coordinate laser station, Leica TDRA 6000, as an alternative for measurements performed by precise levelling. An original approach to the stabilisation of measurement points is presented and technical guidelines for measurements are provided. An analysis of the data obtained from the measurements allowed us to formulate conclusions regarding the measurement technology in question and the accuracy of the results.
