Abstract
As dams are subjected to potential risks, constant monitoring is indicated to avoid disasters. Thus, monitoring these structures is specially important. Specific instruments, as extensometers and pendulums, are installed in the dam during its construction; however the analysis of their measurements only allows discriminating located situations, or relative displacements between given points. Several geodetic techniques can also be applied to monitor their etructures. This work presents a methodology for monitoring poitns in dam inspection galleries using traversing techniques. Our objective is to develop a methodology to monitor these points using precise traverses, to present systems for data process and collection, as well as to developed instruments for this aplication, such as: adaptable devices for forced centering into galleries and specific systems to improve the quality of angular sight. As a case study we show a traverse projected for monitoring located poitns in the inpection galleries of Salto Caxias U. H., in the municipality of Capitao Leonidas Marques, Parana.
