La tecnología DGPS en la construcción: control de movimientos en grandes estructuras

The joint development of auscultation and communications technologies is enabling the development of Automated Monitoring Systems for structures. In this paper, we analyze the viability of the application of DGPS (Differential GPS) technique to monitoring in construction. We can affirm DGPS is accurate and useful for the auscultation of large structures, such as dams, reflecting properly their movements and deformations, compared to geotechnical sensors. The use of DGPS technology in large structures can provide information on the dynamic characteristics of their movements and deformations. All this can be analyzed in real time, with automated measurement systems and alarms programmed for different thresholds. Therefore DGPS is considered a complementary technique for auscultation of large structures that can integrate with other geotechnical or topographical methods, both in the construction and monitoring phases.
