【摘要】 绥江金沙江大桥主桥为一孔150 m的空腹式钢筋混凝土箱形拱桥,工程场地的地震基本烈度为Ⅷ度。由于现行的《公路工程抗震设计规范》(JTJ 004—89)技术比较落后,故参考在编的《公路桥梁抗震设计细则》和国外相关规范,对绥江金沙江大桥进行抗震分析和抗震性能评价,可为类似桥梁的抗震设计提供参考。更多还原

【Abstract】 Suijiang Jinshajiang River Bridge is an open spandrel reinforced concrete box arch bridge with the span of one opening of 150m and the basic seismic intensity on project site is Ⅷ degrees.Since the technology of the existing Specifications of Earthquake Resistant Design for Highway Engneering(JTJ 004—89) lags behind,this paper carries on the seismic analysis and performance evaluation of Suijiang Jinshajiang River Bridge by referring to Guidelines for Seismic Design of Highway Bridges under compilation and relevant foreign specifications.The analysis and evaluation in the paper can provide reference for the seismic design of similar bridges.更多还原
