ASPECTS REGARDING THE ANALYSIS OF HORIZONTAL DISPLACEMENTS AT CUMPĂNA DAM, ARGEŞ COUNTY

Abstract

The paper presents the tracking of the behavior in time of Cumpăna Dam by establishing the horizontal displacements (dx and dy) compared to the base tranche and the previous tranche, and also the processing of these measurements and establishing conclusions and recommendations regarding the behavior of the objective taken into study. The planimetric tracking network used in the case study consists of 7 pilasters and 25 tracking marks. The azimuth and zenith observations made in the case of Cumpăna Dam were conducted with the total station of geodesic order, Leica TM 30 which provides an angular accuracy of 0.5 " or 1" and a distance measuring accuracy of 0.6 mm + 1 ppm on the prism, respectively 2 mm + 2 ppm to any surface. A condition for the accurate determination of absolute displacements of the construction is the stability of geodetic network points. The compensation of the micro-triangulation network was performed in block, using the least squares method.
