Loading Test and Long-Term Monitoring on Wugu-Yangmei Viaduct of Taiwan National Highway

Wugu-Yangmei Viaduct Bridge is the second widening project of Taiwan National Highway. The viaduct stretches from Wugu in the north to Yangmei in the south on the west coastal plain of the island, with the total length of 39 km. It was constructed from November 2009 to December 2012. Before the official opening to the public, the bridge owner, Taiwan Area National Expressway Engineering Bureau, entrusted NCREE with loading tests on the bridge. Besides, after the opening, the deflected shapes of three spans are long-term monitored by optic fiber sensors. This paper describes the mentioned loading tests and optical instruments application in the field.
