斜交桥震害特点与抗震设计初探
|
摘要
基于对"5·12"汶川地震及国外地震中部分斜交桥的震害调查,对斜交桥的震害特点、发生机理及影响因素进行分析和总结,并简要介绍国内外规范中关于斜交桥抗震设计的规定,提出斜交桥抗震设计的注意事项和需要进一步深入研究的问题。
On the basis of investigation for seismic hazards on part of skew bridges in "5·12" Wenchuan earthquake and foreign earthquakes,this paper analyzes and summarizes the features,occurrence mechanisms and influencing factors of seismic hazards on skew bridges,simply introduces the provisions on seismic design of skew bridges in domestic and foreign specifications,and proposes precautions in seismic design of skew bridges and problems for further study.
