Sichuan China's Bridges: Baiyun Bridge in Mianyung (1)

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.
