Abstract

Izveden je bil deformacijski obremenilni preizkus betonske plošče. Betonska plošča je bila obremenjevana z računalniško vodenim hidravličnim valjem PZ 100do sile 42 kN. Uporabljen je bil elektronski tahimeter znamke Nikon 800 in fotoaparat Fuji Pro S3. Izmerila se je vsaka dodatna obremenitev po 3 kN. Uporaba elektronskih tahimetrov za takšne namene je kar pogosta, vendar se v kombinaciji z digitalno fotogrametrijo le redko pojavlja. Kombinacija je zelo obetavna, saj je bil standardni odstopek fotogrametričnih meritev 0,16 mm, geodetskih meritev pa 0,7 mm, opazovanja pa so lahko bila izvedena tako za signalizirane in nesignalizirane točke hkrati. Betonska plošča je bila dodatno tudi analitično zmodelirana, model pa se je primerjal s fotogrametrično, geodetsko in hidravlično metodo.

Secondary title: Najsodobnejše metode merjenja deformacij in njihova primerjava
Secondary abstract: Deformation measurement experiment has been undertaken where a concrete structure was subject to controlled loading. Concrete plate was loaded with hydraulic cylinder PZ 100 up to 42 kN. Nikon total station ser. 720 and camera Fuji Pro S3 have been used to make measurements at critical points during each additional load. A hydraulic computer operated cylinder was used for load increase. The use of total stations for deformation measurements is quite often, but the combination with digital photography is rather new and very suitable technique. It offers the capability of simultaneous monitoring of a large number of signalized or non-signalized points with very low root mean square error of 0.16 mm in geodetic method 0.7 mm in photogrammetry, respectively. The concrete plate was modeled and the comparison with the geodetic, photogrammetric and hydraulic method was made.
