摘要
铁路桥梁抗震设计的效果直接影响工程结构的抗震性能。文章基于我国《铁路工程抗震设计规范》标准要求,分析目前铁路桥梁抗震设计的问题和不足,发现目前有5%的铁路桥梁缺少多遇抗震设计性能、11%的铁路桥梁缺乏设计地震的水平、8%的铁路桥梁缺乏罕见地震的水平,不能确保抗震性能符合标准。为增强铁路桥梁的安全性,在未来发展的过程中应明确抗震设计思路,保证设计的科学化水平。
The effect of anti-seismic design of railway bridge directly affects the anti-seismic performance of engineering structure.Based on the standard requirements of Code for Anti-seismic Design of Railway Engineering,this paper analyzes the problems and shortcomings of current anti-seismic design of railway bridges.It is found that 5%of railway bridges are lack of frequent anti-seismic design performance,11%of railway bridges are lack of earthquake level design,and 8%of railway bridges are lack of rare earthquake level,which cannot ensure that the anti-seismic performance meets the standard.In order to enhance the safety of railway bridges,the anti-seismic design idea should be clarified in the process of future development to ensure the scientific level of design.
