Development of Bridge Deflections in the 24-hours Cycle

Popis výsledku v původním jazyce

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, therefore a periodic geodetic measurement observing progression of the deformations should be implemented. The main results of measurements are the changes of the deflection line of the bridge structures, which places special demands on the measurement procedure. In order to reliablydetermine the deflection curve of the bridge structure, it is necessary to minimize the effects of temperature. Development of air temperature and bridge construction is generally different. To determine the optimum time for measuring the deflection, theanalysis of the bridge structure was made in 24-hours cycle. Development of deflection was measured by trigonometric method and method of laser scanning.
