Geodetic surveying of railway objects

摘要

The paper includes the description of geodetic activities using computer and plotting support for the construction of the traffic objects in the railway engineering. The main principles of monumentation and adjustment of the setting-out network are presented among the most common kinds of surveying methods. The requirements for the apparatus equipment and its precision of measurement. Two step setting-out of the traffic objects and control measurement during their construction process. The measurement of deformation values during the load test of constructions. The relation of the required accuracy between deformation values and surveying accuracy. The cyclic measurement for the purposes of the diagnostions. The relation of the required accuracy between deformation values and surveying accuracy. The cyclic measurement for the purposes of the diagnostics of the spatial traffic objects changes. Geodetic surveying using computer support for the construction of bridges across the river Vah in Zilina. The software utilization support for the geodetic survey and cartographic work for the railway engineering.
