哪里有关于这座桥的信息。
这可是桥梁动荷载
Adolphe Bridge was first renovated in 1961, and minor changes were made again in 1976. In 1990, the Luxembourgian government launched an investigation into the state of the bridge, and found that it showed signs of extensive damage, to both the stonework and steel. Between September 2003 and August 2004, the central arches were strengthened by the addition of 258 prestressed steel bars, with a total force of 25,600 tonnes (251,000,000 N). |
