| July 2008 (31.4547°N, 104.7177°E) Baiyun Bridge |
Baiyun Bridge is a three span, simply supported, arch
bridge with prestressed tendons at the deck to keep the arch in
compression. The arches are supported on
four-column bents and seat type abutments.
After the earthquake, oil in the tendon ducts began to leak, suggesting
that the ducts had developed cracks during the earthquake (or possibly the
anchorages were damaged). Also, there was
some spalling of the deck around the arches and cables. Mianyung was in the plains and far from the area of strong shaking.
