Résumé:
In this dissertation, a survey of the dams constructed in the state of Paraíba was carried out. Due to the large numbers, only those that had the essential designs and parameters of the soils with which they were built were selected. The present work was complemented by an in-situ study of the geotechnical characteristics of the dams and laboratory studies with tests to determine the parameters of compaction, granulometry, plasticity, permeability, cohesion and internal friction angle of the soils of the selected dams. The stabilities of the dams for
periods of construction and full reservoir, using the simplified Bishop method, with the help of a computer program. The obtained results allowed to conclude that, in most of the studied dams there is no discrepancy
of the original project data with those determined in the present research.
Regarding the dams visit program, it can be seen that all the dams selected for this research have deficiencies in maintenance,
already entailing, in some dams, problems of a technical nature.
