Geodetic methods are one of the possible means of determining the stability of geotechnical objects. The determination of the displacements of the geotechnical objects is specific due to the size and the expected displacements. The expected size of the displacement determines the necessary precision of the displacement determination, whereas the size of the object determines the method of the geodetic measurement. We choose either the terrestrical or the GNSS methods. There is no relevant legal framework for geotechnical measurements. For this reason, we present the characteristics of the single methods and suggest general recommendations regarding the implementation of the geodetic procedures when monitoring the displacements of the geotechnical objects. The recommendations are intended for geotechnical engineers planning the geotechnical objects and the operators of geodetic measurements and investors. The recommendations the facilitate supervision of the geotechnical projects.

Abstract

Geodetske metode so eden od možnih načinov za ugotavljanje stabilnosti geotehničnih objektov. Spremljanje premikov geotehničnih objektov je zaradi velikosti objektov in pričakovanih premikov nekoliko specifično. Pričakovana velikost premikov določa potrebno natančnost določitve premikov, velikost objekta pa določa metodo geodetske izmere. V osnovi izbiramo med terestričnimi metodami in metodami GNSS (globalni navigacijski satelitski sistem). Ker za izvajanje geotehničnih meritev ni ustrezne zakonske podlage, predstavljamo posebnosti posameznih metod in navajamo splošna priporočila za izvedbo geodetskih postopkov pri spremljanju premikov geotehničnih objektov. Priporočila so namenjena projektantom geotehničnih objektov in izvajalcem geodetskih del ter investitorjem, ki jim lahko olajšajo nadzor nad izvajanjem geotehničnih projektov.
