Analisi con software scientifici di una rete GNSS per il monitoraggio di deformazioni strutturali

Abstract

Nel presente articolo viene analizzata una rete GNSS realizzata per il monitoraggio delle deformazioni di due viadotti autostradali. Sulla rete è stata eseguita una misura iniziale di zero e successive campagne di misura a cadenza circa semestrale, con ricevitori a doppia frequenza GPS/GLONASS, in modalità statica. Vengono qui analizzate in particolare le soluzioni ottenute con il software Bernese 5.0 per la misura di zero e una delle campagne successive, valutando l’effetto e la convenienza di diverse opzioni e modalità di calcolo, ed effettuando un confronto con le soluzioni ottenute con altri software. Sono state inoltre sviluppate alcune procedure software che partendo dalle soluzioni Bernese 5.0 e rispettive matrici di covarianza effettuano analisi e test statistici finalizzati a verificare l’attendibilità o meno delle deformazioni rilevate dal confronto tra le soluzioni. Il lavoro presenta i risultati ottenuti mediante le procedure sopra menzionate, eseguendo un confron-to con quelli ottenuti da altri software a carattere tecnico comunemente utilizzati per applicazioni come quelle in oggetto.
