Abstract

Έλεγχος μετακινήσεων της Κρηπίδας του Ναού του Ολυμπίου Διός.

The present dissertation deals with the detection of the (possible) vertical displacements of the crepis of the temple of Zeus in Athens (Olybeion) using geodetic methodology. For this purpose a vertical control network is established on the euthynteria level of the temple’s crepis consisting of 13 points as a whole. The network’s elements (height differences) have been measured using double geodetic leveling. The heights of the network points are estimated using least squares adjustment. These heights are compared with those obtained from the previous two measuring campaigns (June and September 2001). Finally the statistically significant vertical displacements are estimated using appropriate statistical tests. The dissertation consists of the following 11 chapters : The first chapter deals with the purpose of the dissertation, while in the second chapter the architectural features of the ancient Greek temple as well as the main three orders of the ancient temples’ columns are presented. A brief history of the temple of Zeus in Athens (Olybeion) is also given. The third chapter deals with the Athenian underground geology while in the fourth chapter the geodetic methodology used for the construction monitoring is presented. The fifth chapter deals with the features of the vertical control network established for the monitoring of the vertical displacements of the temple’s crepis and in the sixth chapter the network’s pre-analysis is given. The seventh chapter deals with the instrument used for the measurements, and the results of the measuring procedure. In the eighth chapter the results of the network’s adjustments are presented. Using these results in the following ninth chapter the statistically significant vertical displacements are estimated for a specified level of significance. Finally in the eleventh chapter the conclusions withdrawn are given.
