摘要
川藏铁路藏木雅鲁藏布江特大桥采用430m中承式钢管混凝土拱桥跨越雅鲁藏布江,桥位处地震动峰值加速度为0.24g,为8度地震区,桥梁抗震设计控制大桥结构设计。设计采用非线性时程分析法,研究分析了结构采用不同减隔震措施组合后的减隔震性能。研究表明:黏滞阻尼器和软钢阻尼器能有效控制罕遇地震下的主梁位移,与摩擦摆支座组合使用,可显著提高该桥抗震性能。
Sichuang-Xizang railway Zangmu Yarlung Zangbo River Bridge spans the Yarlung Zangbo River using a half-through concrete filled steel tube arch with a span of 430 m.The peak acceleration of ground motion at bridge site is0.24 g and eight degree earthquake zone,seismic design control the bridge structure design.Nonlinear time history analysis method is adopted in the design,and the seismic isolation performance of the structure with different combination of seismic isolation measures is studied and analyzed.Research shows:Viscous damper and hysteretic damper can effectively control the displacement of main girder under rare earthquake,the seismic performance of the bridge can be significantly improved with the combination of friction pendulum bearing.
