ABSTRACT

The main goal of the repeated geodetic observations for displacement and deformation
analysis is to ensure the stability and the good functioning of the activities of the
observed objective, but also protecting the environment. Beside the functional role of
the hydropower buildings, these produce important effects on the environment and
surrounding areas. In order to avoid any events that may cause severe catastrophes, the
monitoring of these buildings is required, starting with the execution phase, during the
usage and post-usage phase. Based on the mathematical statistics principles, conclusions
can be drawn about the nature of displacements and deformations suffered by the
observed objective. The main steps of the displacement and deformation analysis are:
geodetic observations adjustment, for each measurement epoch, homogeneity testing of
the monitoring geodetic network, congruency testing of the monitoring geodetic
network, and, if needed, localization of the points with significant displacements. As a
case study, we chose the Tău Dam, included into the Hydropower Complex Şugag-Tău,
Sebeş Valley, Alba County, Romania.
