Opis:
Prestressed concrete bridges are very sensitive to the increase in long-term deflections. Reliable forecasts of deflections of bridge structures during construction and durability are crucial for achieving good durability. The main results of measurements are the changes of the deflection line of the bridge structures, which places special demands on the measurement procedure. Results from measurements are very useful for the improvement of mathematical prediction methods of behaviour of long span prestressed concrete structures.

Opis:
Control points are inseparable components of the laser scanning measurement process. They are mainly applied to connect point clouds from various standpoints. These points also ensure control in transformations of individual scanning positions and thus significantly affect the accuracy of the whole processing. This article deals with the evaluation of the accuracy of control points’ position determination using the Leica HDS 3000 laser scanning system. For this purpose, a special measurement experiment was designed and performed in which a geodetic network consisting of control points of various design and produced by various manufacturers was measured. The measuring experiment checked the “internal accuracy” (by repeated measurements) of the determination of control points’ coordinates using the laser scanning method; furthermore, the accuracy of coordinates determined by the laser scanning method was compared with the coordinates measured by the total station. Coordinates determined by means of laser scanning from different standpoints were mutually compared. Last, but not least, the instrument accuracy declared by the manufacturer was monitored and compared with the results of measurements conducted in laboratory conditions. Five types of control points were used for this experiment. Then, the position determination accuracy was evaluated in relation to individual types of control points used.

Opis:
The paper deal with testing of different GNSS measurement methods in highly accurate network for the objectives engineering surveying. The test is comprised of a set of measurement acquired by particular GNSS methods with different observation length. For purposes of the test, an appropriate network of five points in local system was created and accurately trigonometrically measured. The result of testing is a comparison of individual methods in position using two dimensional congruent transformation and in height using one dimensional congruent transformation.
