ON THE POSSIBILITY OF GEOMETRIC CHANGES OF LARGE DAMS DETERMINATION BY GEODETIC METHODS

Abstract

Large dams are exposed to the influence of various forces which in time cause changes in their position and geometry. Knowledge about changes in position and geometry of large dams is of crucial importance for their stability and security determination. Dams, in process of deformation analysis, are approximated by set of discrete points and on the base of the changes in position and through time of those points the conclusions of changes of dam position and geometry are made. For large dams' security of highest importance is to detect changes of position and geometry where they are small in order to discover the negative trends and to take measures for prevent consequences of jeopardized dams' security in time. This paper investigates the possibilities of dams' geometry changes detection on the base of geodetic measurements.
