The RION-ANTIRION Bridge (Greece) is located in a zone of difficult environmental conditions characterised by deep soil strata of weak alluviums, large depth of water and strong seismic design motion. All these constraints have called for an original design presenting innovative features, such as big, 90 m foundations, resting on soil reinforced by means of metallic inclusions and continuous cable-stayed deck, fully suspended for its total length of 2,252 m. Construction methods are also unconventional, particularly for preparation of the seabed.

Materials

3. This project quite complex:
• large water depth (up to 65 m)
• deep soil strata of weak alluviums
• a strong seismic activity
• possible tectonic movements

4. Concept
• Hanger
• Pepsi bottele
• Sprinlke system
• Chimney

5. 1 Logic
• Silty clay -liqufiction-
• Quick sand condition—Japan earthquake
• Concept used – Vital grass root (7m long)

6. 2. Logic
Topling
• Each pier moves freely

7. 3. Logic
• Deck movement in earthquake zone
Deck free to move
Viscus damfer- control the movement
Control the movement – Sprinkling –(60-68*C)
Pepsi bottel

8. 4.Logic
• Cables
1997- wind effect
Chimney – helical strips
