This project quite complex:• large water depth (up to 65 m) • deep soil strata of weak alluviums• a strong seismic activity• possible tectonic movements
Concept
• Hanger• Pepsi bottele• Sprinlke system• Chimney
1 Logic
• Silty clay -liqufiction-
• Quick sand condition—Japan earthquake
• Concept used – Vital grass root (7m long)
2. Logic
Topling • Each pier moves freely
3. Logic
• Deck movement in earthquake zoneDeck free to moveViscus damfer- control the movement Control the movement – Sprinkling –(60-68*C)Pepsi bottel
4.Logic
• Cables 1997- wind effect Chimney – helical strips
SILT CLAY SOLUTIONLIQUIFICATION
USE THE NEW CONCEPT & DEVELOP
