Problem bočne refrakcije v predoru : diplomska naloga

Slemenšek, Nejc (author), Ambrožič, Tomaž (mentor), Štebe, Gašper (co-mentor)

V diplomski nalogi smo želeli dokazati vpliv horizontalne oziroma bočne refrakcije na merjene horizontalne smeri v predoru. Na začetku naloge je na kratko opisana lokacija, kjer se predor nahaja, ter nekaj njegovih osnovnih tehničnih karakteristik. Predstavljena je tudi vertikalna refrakcija in bočna refrakcija, ki je osnova za to diplomsko nalogo. Opisan je instrumentarij in pribor, ki je bil uporabljen pri izmeri geodetske mreže. Po splošni razlagi, je opisana izvedba in metoda meritev ter obdelava podatkov meritev (izračun sredin girusov, redukcija poševno merjenih dolžin, izračun natančnosti vseh meritev). Opisan je postopek izračuna dveh variant poligona in izravnave geodetske mreže. Grafično in numerično je prikazana razlika med obema poligonoma ter geodetsko mrežo, ki je izračunana na zadnji točki poligonov oziroma geodetske mreže. Za konec so predstavljene ugotovitve ter predlogi, kako bi izbrali najboljšo varianto poligona oziroma geodetske mreže.

• Title: Problem of lateral refraction in the tunnel : graduation thesis

Abstract

In thise thesis we wanted to prove the influence of horizontal or lateral refraction on measured horizontal direction in the tunnel. At the begining the location of the tunnel is briefly described and some of its basic tehnical characteristics. Vertical and lateral refraction are presented. Lateral refraction is the basis for this thesis. Instruments and accessories we used while measuring geodetic netword are described as well. After general explanation, the execution of measurement, the method of measurement and processing of measurement data are described (calculating set of angles, reduction of measured lengths, calaculation of accuracy of all measurements. Procedures for calculating two versions of geodetic polygons and leveling a geodetic network are described. Graphically and numericaly, the difference between the two polygons and the geodetic network is shown, calculated on the basis of the last point of the polygon or geodetic network. At the end, the findings and suggestions on how to choose the best version of the polygon or geodetic network are presented.

• Keywords: Lateral refraction, tunnel, geodetic network adjustment, set of angels, horizontal angle, vertical angle, reduction of the lenght.
