Il controllo dei movimenti e delle deformazioni si basa sul confronto fra rilievi ripetuti in diversi momenti ed in particolare sulla determinazione della variazione delle coordinate di un numero prestabilito di punti, opportunamente individuato in precedenza. Il metodo topografico rappresenta una delle possibili soluzioni per raggiungere tale fine. Una rete di controllo è costituita da vertici di riferimento (punti ubicati in zone ritenute stabili) e da vertici di controllo (punti ubicati in zone ritenute non stabili, all’interno della zona oggetto di monitoraggio). I movimenti da individuare possono essere di due tipologie: “relativi” fra i punti di controllo ed “assoluti” dei punti di controllo rispetto ad una struttura stabile ovvero rispetto alla rete di riferimento. Obiettivo del presente lavoro è verificare la stabilità nel tempo di una rete di riferimento costituita per il monitoraggio di una zona soggetta ad eventi franosi, attraverso l’impiego sui dati GPS a disposizione sia dell’approccio inferenziale classico che bayesiano. L’applicazione del teorema di Bayes ha confermato l’assenza di fenomeni deformativi.

Abstract
The control of movements and deformations is based on the comparison between surveys repeated in different times and in particular on the determination of a certain number of points. The topographical method represents one of the possible solutions in order to reach such aim. A control network is constituted by reference points (located in stable zones) and by control points (located in not-stable zones). The movements can be of two kinds: “relative” between the control points (network deformations) and “absolute” (control points respect to the reference network). It’s necessary, therefore, to estimate, during the time, the stability of reference points. In this paper, it was investigated the stability of reference network, located in Senerchia (Sothern Italy) and constituted for the monitoring of a landslide area. The survey has been executed with static GPS. It has been executed on the network both the classical and the Bayesian statistical analysis in order to quantify the movements and to identify small movements in comparison with accuracy of the measurements. The application of the Bayes theory on the network has confirmed its stabilityI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
