DETERMINING OF PLATE FLATNESS
Original language description
In many cases the measurement of relative flatness in engineering geodesy is necessary. For bridge construction are used bearings, which must be placed to horizontal plate. The segment of bridge is usually measured in production hall, where plates for bearing are not in horizontal plane (the plates are settled in general plane, but the plane is almost horizontal). The paper presents several measurement methods for determining of relative plate flatness. In this case the main problem is achievable accuracy. The measured plate is usually relatively horizontal (bridge plate for bearings) and then leveling and spatial polar method for measuring are used. For determining of achievable accuracy the experiment was done. The plate with hundred points for testing selected methods was made. Digital leveling, optical leveling and spatial polar method (automatic to prism, hand to prism and hand to reflective target) for experiment were chosen. The standard deviation of methods from difference between two measurements was calculated. The flatness of plate of each method from average height was calculated. The individual methods with using robust weighted average were compared. The comparison of deviations from the fitting plane was done too.
