Περίληψη


Η παρούσα μεταπτυχιακή διατριβή αποτελεί μελέτη περίπτωσης με αντικείμενο τη διερεύνηση της  εφαρμοσιμότητας των παρακάτω γεωφυσικών μεθόδων σε περιβάλλον σήραγγας. Συγκεκριμένα, της μεθόδου του γεωραντάρ και της ηλεκτρικής τομογραφίας, σε συνδυασμό με τη μοντελοποίηση δεδομένων γεωραντάρ. Η περιοχή έρευνας όπου έλαβε μέρος η διασκόπηση είναι η σήραγγα που βρίσκεται στην περιοχή των καταρρακτών της Έδεσσας. Από την έρευνα που πραγματοποιήθηκε στο δυτικό τοιχίο της σήραγγας χαρτογραφήθηκε ο μεταλλικός οπλισμός, το πάχος του οπλισμένου σκυροδέματος, η επαφή του σκυροδέματος με την τραβερτινική βραχόμαζα, ζώνες υγρασίας καθώς και πιθανές ασυνέχειες στον τραβερτινικό σχηματισμό. Οι παραπάνω γεωφυσικές μέθοδοι αποδείχτηκαν αποτελεσματικές καθώς συνέβαλαν συνδυαστικά στη χαρτογράφηση πολλαπλών εσωτερικών δομών. Η μοντελοποίηση δεδομένων συνετέλεσε σημαντικά ως προς την ερμηνεία των γεωφυσικών προφίλ και συνείσφερε στην εξαγωγή συμπερασμάτων.

This master's thesis is a case study to investigate the applicability of the following geophysical methods in a tunnel environment. Specifically, the method of geo-radar and electrical tomography, in combination with the modeling of geo-radar data. The research area where the survey took place is the tunnel located in the area of the waterfalls of Edessa. The research carried out on the western wall of the tunnel mapped the metal reinforcement, the thickness of the reinforced concrete, the contact of the concrete with the travertine rock mass, moisture zones as well as possible discontinuities in the travertine formation. The combination of the above geophysical methods proved to be effective as it resulted to the mapping of multiple internal structures. Data modeling contributed significantly to the interpretation of geophysical profiles and contributed to the conclusions.
