Sekundarni naslov: Research of horizontalni displacements in network Gameljne
Sekundarni povzetek: The discussed network Gameljne is one of the three smaller networks of seismic nets along the tectonic fault of Ljubljana for the determination of horizontal displacements. It is the most northern network of those three. It consists of four points in a shape of a rectangular with only one diagonal. The network has been, including this year, measured six times. Horizontal and vertical angles and slope distances are measured in the network. The basis for displacement determination is the first measurement, with which all subsequent measurements performed in selected time intervals are compared. In addition to precise measurements, the stability of the measurement points is also very important so that we can determine even the smallest displacements with the highest probability. The result of processing the measurements are definite coordinates of points. From the differences of the coordinates the horizontal displacements in the y and x axes direction are defined and with adding both vectors we can obtain the entire displacement. The displacement of points can be detected with sufficient certainty only when the displacements are significantly higher than the accuracy of estimated displacements. The accuracy of displacement depends on the accuracy of determining the position of points in the first series of measurements and the accuracy of determining the position of point in the ongoing series of measurements. By improving the accuracy of the measurements it would not relatively increase the accuracy of determining individual points, because it is burdened with the accuracy of the determination point in the first measurement.

Povzetek (ePrints): Obravnavana mreža Gameljne je ena izmed treh manjših mrež ob ljubljanski prelomnici za določanje horizontalnih premikov. Izmed vseh treh leži najseverneje. Sestavljena je iz štirih točk in ima obliko četverokotnika z le eno diagonalo. Mreža je bila vključno z letošnjo izmero izmerjena šestkrat. V mreži so opazovani horizontalni ter vertikalni koti in merjene dolžine. Osnova za določitev premikov je prva izmera, s katero se primerja vse kasnejše meritve, opravljene v izbranih časovnih intervalih. Da lahko z največjo verjetnostjo določimo zelo majhne premike, je poleg precizne izmere in izravnave prav gotovo izredno pomembna lastna stabilnost merskih točk, s pomočjo katerih opišemo premike. Rezultat obdelave meritev in izravnave so definitivne koordinate točk. Iz razlik teh koordinat so računani horizontalni premiki v smeri osi y in x, z vektorskim seštevanjem obeh vektorjev pa je mogoče dobiti celotni premik. Premike točk je mogoče z zadostno verjetnostjo odkriti šele tedaj, ko so premiki statistično značilno večji od natančnosti ocene premikov pri izbrani stopnji značilnosti testa. Natančnost premika je odvisna od natančnosti določitve položaja točke v prvi seriji meritev in natančnosti določitve položaja točke v tekoči seriji meritev. S povečanjem natančnosti merjenj se ne bi sorazmerno povečevala tudi natančnost določitve premika posamezne točke, saj jo obremenjuje natančnost določitve položaja te točke v prvi seriji meritev.
