Vertical movements of tripods and their effect on the results of precise leveling measurements
Original language description
All surveying measurements take place in an environment which affects the results obtained through its physical properties. Many of these effects are reflected in the results as random or systematic errors, which reduce the measured variable's precision. Tripod instability during measurements can be observed due to deflection of the surveying instrument's level duringmeasurements, or after finishing the measurements at the given position. Height changes in the instrument can be caused by settling (lowering) or lifting (raising) the tripod's legs under the action of the soil's elastic properties. Alternatively, the tripod may be deformed due to changes in the physical parameters of the environment. This study aimed to determine the size of instrument height changes resulting from all three tripod leg movements in a vertical direction. The magnitude of the difference in the instrument's horizontal line depends mainly on the soil's mechanical properties and the time required for the operation at the given position. The rate of height change was not constant. Tripod height increase was stabilized afterabout 15 min at approx. 0.03 mm (in summer) and 0.05 mm (in autumn). In winter, the height of the tripod increased by only 0.01 mm. Statistical testing of the experiment's resulting design revealed a significant effect of soil moisture, temperature,and type on changes in the leveling instrument's horizontal axis.
