GEODETIC WORKS IN THE DESIGN AND STRUCTION OF TUNNELS

Geodetska stroka je pri projektiranju, gradnji in uporabi predorov nenadomestljiva. Še posebno pri geološko nestabilnih tleh se pokaže pomembnost vloge geodezije, saj so konstantne kontrolne meritve za stabilno izgradnjo predora neizogibne. V teoretični del diplomske naloge opredeljuje osnove in postopke potrebnih geodetskih del v celotnem ciklusu gradnje predorov. Kritičen del predstavlja natančnost pri preboju, zato je njej potrebno posvetiti posebno pozornost. Opisane in primerjane bodo različne tehnologije gradnje ter geotehnične raziskave in njihov pomen. Praktični del prikazuje potek kontrolnih meritev pomikov na betonskem okvirju za potrebe gradnje predora med Medicinsko fakulteto in Univerzitetnim kliničnim centrom Maribor.Surveying profession is irreplaceable in designing, building and operating of tunnels. Importance of geodesy is especially shown in geologically unstable ground, where the constant control measurements are essential for stable construction of a tunnel. Theoretical part of the thesis describe bases and procedures of geodetic works, which are necessary throughout the whole cycle of building of a tunnel. Critical part by breakthrough of a tunnel is precision, so it is necessary to pay attention at it. In addition, the various technologies of the construction, geotechnical surveys and their importance are described and compared. Practical part of the thesis demonstrate the progress of control measurements of displacements on concrete frame for the construction of a tunnel between Faculty of Medicine and University Medical Centre Maribor
