广东省桥梁抽样调查与地震易损性评价

Sample Survey and Seismic Vulnerability Evaluation of Bridges in Guangdong Province

结合广东省水系分布抽样定位代表性大型、特大型桥梁位置,并在此基础上进行现场调研,着重了解这些大桥的基本属性和使用现状,同时借鉴四川汶川地震震害资料分析桥梁震害特点,进一步对所调查的桥梁做群体地震易损性分析,从而给出主要病害成因,提出完善桥梁设计理念和防震措施的一些意见。

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.
