【摘要】 《铁路工程抗震设计规范》(GBJ 111-87)与《铁路工程抗震设计规范》(报批稿)在现阶段铁路桥梁设计中的安全度究竟如何?一直被建设者和设计者所关心。结合京沪高速铁路济南黄河大桥的结构抗震性能研究,通过对结构的抗震设防标准、地震作用大小、结构验算准则等几方面进行分析比较,指出上述2个规范的结构抗震安全性的差异。更多还原

【Abstract】 The issue of how the safety degree in both editions of Code for Seismic Design of Railway Engineering(GBJ 111-87) and(Revision for Approval) is in the current design of railway bridges has been a matter of concern of constructors and designers of the bridges.In this paper,in the light of the research of the structural seismic resistance of Ji’nan Huanghe River Bridge on Beijing-Shanghai High Speed Railway,and through the analysis and comparison of the seismic protection criteria,seismic action scale and checking criteria of bridge structures,the differences of the structural seismic resistance safety in the above-mentioned Code of the two kinds of editions are pointed out.更多还原
