| Abstract: | The Paper firstly fixes the locaitons of the large and mega bridges based on the river system in Guangdong,then site surveys were conducted accordingly to learn about the basic attributes and existing use conditions of these bridges.Then the Paper analyzes the characteristics of seismic damage to the bridges and the group seismic vulnerability of the surveyed bridges with reference to the seismic damage data of the Wenchuan Earthquake,and finally summarizes the major causes for the damage and put forward some opinions on perfecting the bridge design concept and seismic countermeasures. |
