Sažetak
The determination of deformation on construction objects referring to a certain line, when various load are involved has been made automatic at the Faculty of Geodesy, University of Zagreb by means of electronic theodolite Leica (Kern) E2 and on-line laptop. In order to achieve as high accuracy as possible, it is possible to perform fine pointing 2 to 10 times as selected. The reading of the horizontal and vertical angle enters automatically into the computer, and the deformation is computed with the distance measured to the target and entered before the measuring started, as related to the reference measurement. During the test loads it is possible to have graphically presented differences in deformation between various test loads phases displayed after the measurement in every phase. In case that the deformation is too large, one can immediately stop to increase the test load. During the first test observations in Kaštela, while testing the change of deformations on the pier for loading and unloading by applying the change of test loads, this method has proved as very practical. The standard deviation in determining the shift at the distance of 50 m with one fine pointing on to the target has reached 0.2 mm, and with more fine pointings, it can be expected to go below 0.1 mm.
