Resumo: | This article analyzes the influence of external agents during the geodetic monitoring of structures, a case study at the dam of the Hydroelectric Power Plant (UHE) in Mauá-PR, combining the satellite positioning method using GNSS with the irradiation method using robotic Total Station for determine eventual movements of monitoring points embedded in the dam parameter downstream and in the crest of the upstream bus. The procedures adopted consist of comparing the results of the monitoring carried out with the spillway gates opened with the results of the same monitoring carried out with the spillway gates closed and, consequently, analyzing whether the opening of the spillway interferes with the geodetic monitoring since, the spillway located in the center of the dam. Parallel to this, with the same equipment, the monitoring of points embedded in the crest of the upstream dam was carried out from two pillars, one on the left bank, another on the right bank of the reservoir and two systems of forced centering on the dam. After processing the data, analyzes were made where it was found that the fact that the dam has an open spillway affects the determination of the coordinates in the body of the dam downstream, presenting values significantly different from the coordinates with the open or closed spillway. It was also observed that depending on the point of the geodetic network used to determine the coordinates of the points on the crest of the dam, right, left margin or on the dam the coordinates also show significant variations. |

Los procedimientos adoptados consisten en comparar los resultados del monitoreo realizado con las compuertas del aliviadero abiertas con los resultados del mismo monitoreo realizado con las compuertas del aliviadero cerradas y, en consecuencia, analizar si la apertura del aliviadero interfiere con la precisión de la geodésica. monitoreo, ya que el aliviadero está ubicado en el centro de la presa. Luego de procesar los datos, se realizaron análisis donde se encontró que el hecho de que la presa tenga un aliviadero abierto afecta la precisión de las coordenadas en el cuerpo de la presa aguas abajo, presentando valores significativamente diferentes a las coordenadas con el aliviadero abierto o cerrado. Paralelamente, con el mismo equipo se realizó el seguimiento de puntos incrustados en la cresta de la presa aguas arriba, donde se observó que dependiendo del punto de la red geodésica utilizado para determinar las coordenadas de los puntos de la cresta de la presa, derecha, izquierda o sobre la presa las coordenadas también muestran variaciones significativas.Este artigo analisa a influência de agentes externos durante o monitoramento geodésico de estruturas, estudo de caso na barragem da Usina Hidrelétrica (UHE) de Mauá-PR, combinando o método de posicionamento por satélite utilizando GNSS com o método da irradiação utilizando Estação Total robotizada para determinar eventuais movimentos de pontos de monitoramento da barragem. Os procedimentos adotados consistem em comparar os resultados do monitoramento realizado com as comportas do vertedor abertas com os resultados do mesmo monitoramento realizado com as comportas do vertedor fechadas e, consequentemente, analisar se a abertura do vertedor interfere na precisão do monitoramento geodésico, uma vez que o vertedor localiza-se no centro da barragem. Após o processamento dos dados foram feitas análises onde verificou-se que o fato da barragem estar com o vertedor aberto, afeta a precisão das coordenadas no corpo da barragem à jusante apresentando valores significativamente diferentes das coordenadas com o vertedor aberto ou fechado. Paralelamente, com o mesmo equipamento, realizou-se o monitoramento de pontos engastados na crista da barragem à montante onde observou-se que dependendo do ponto da rede geodésica utilizado para a determinação das coordenadas dos pontos na crista da barragem, margem direita, esquerda ou sobre a barragem as coordenadas também apresentam variações significativas.Universidade Federal do Rio Grande do Norte2022-02-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://periodicos.ufrn.br/revistadoregne/article/view/2585710.21680/2447-3359.2022v8n1ID25857Revista de Geociências do Nordeste; v. 8 n. 1 (2022); 47-592447-335910.21680/2447-3359.2022v8n1reponame:Revista de Geociências do Nordesteinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNporenghttps://periodicos.ufrn.br/revistadoregne/article/view/25857/15350https://periodicos.ufrn.br/revistadoregne/article/view/25857/15351Copyright (c) 2022 Revista de Geociências do Nordesteinfo:eu-repo/semantics/openAccessJerke, AndreasFaggion, Pedro Luisda Cruz, Wander2022-03-03T18:02:46Zoai:periodicos.ufrn.br:article/25857Revistahttps://periodicos.ufrn.br/revistadoregne/indexPUBhttps://periodicos.ufrn.br/revistadoregne/oairegneufrn@gmail.com || periodicos@bczm.ufrn.br2447-33592447-3359opendoar:2022-03-03T18:02:46Revista de Geociências do Nordeste - Universidade Federal do Rio Grande do Norte (UFRN)false |
