Determination of the displacements of the barrier at Prigorica

In the graduation thesis we have presented the determining of the displacements of the barrier at Prigorica. Our calculations were made in five term measurements. The thesis constist of the calculation of all combinations between term measurements. The measurements have been made with instruments Leica TC 1700 for angular and linear measurements and nivelir Leica- NAK 2 with a planparalel plate for vertical movements. Before we began analysing the displacements, individual term measurements have been adjustment by least – squares principle. The final adjustment has given us the answer whether there are any gross errors among the measures or observations, the adjusted coordinates and the accuracy analysis. To begin with the analysis of the displacement, we must first ensure, along with the prior adjustment, that the number of points is identical in all term measurements. The choice of method for determination and analysis of the displacement depends on the assignment. For analysing point displacements we have decided for a simple procedure with program Premik and the method of Hannover for a detailed deformation analysis. The method of Hannover is a procedure that reveals and determins the caused displacements with methods of statistical analysis. We test homogenity of accuracy of term measurements, we make a global test of reference points stability and determine and test possible displacements on an observed object. Both procedures are presented in detail in the graduation thesis. For conclusion we have presented the results of analysis and compared them with each other
