Structural Deformation Monitoring Using GPS and Conventional Surveying Methods

Selassie David Mayunga

Abstract: This paper describes the application of Global Positioning System (GPS) and trigonometric levelling for structural settlement monitoring at the Botswana International University of Science and Technology (BIUST). The research provides an overview of previous research on structural deformation monitoring techniques, including the analysis of the advantages and disadvantages of the measurement techniques used. In addition, this paper examined the structural deformation monitoring using GPS and trigonometric levelling and determine the parameters subjected to heavy loads of the structure after being completed. The GPS observation and deformation data were processed and analysed by using the Least Squares Adjustment software. The results showed a correlation coefficient of 0.998, and the computed coordinates of reference and monitoring points revealed a standard deviation of 19.6 cm and a RMSE of 0.131.
