某连续梁桥地震反应谱分析

On seismic response spectrum analysis of some continuous beam bridge

以预应力混凝土连续梁桥为研究对象,根据桥梁所处场地的地质条件,建立有限元空间模型,应用反应谱理论,对其进行地震反应分析,得出一些有意义的结论,结果表明考虑桩—土相互作用会使结构更接近真实情况。

Taking the prestressed concrete continuous beam bridge as the research object,the paper establishes the finite element spatial model applies the response spectrum analysis according to the geological conditions of the field of the bridge,undertakes the seismic spectrum analysis,concludes the significant conclusion,and proves the mutual effect of the pile and soil can make the structure close to the factual situation.
