Identification of soil-structure interaction effects based on geodetic monitoring of a railway bridge
Psimoulis, Panos and Stiros, Stathis and Moschas, Fanis (2014) Identification of soil-structure interaction effects based on geodetic monitoring of a railway bridge. In: 2nd International Conference on Bridges "Innovations on Bridges and Soil-Bridge Interaction", 16-18 Oct 2014, Athens, Greece.
The monitoring of bridges using geodetic methodologies permits the direct measurement of displacements and potential identification of effects of soil-structure interaction. In this study the response of the historical Gorgopotamos railway (Central Greece) has been measured using a Robotic Total Station (RTS) during the passage of trains on different times of the year and under various soil conditions. The measurements revealed that the initial impact response of the deck to the train loading presents differences which seem to correlate with the differences in the moisture content of the bridge foundation ground.
