某公路大桥引桥抗震性能研究

Research on Seismic Performance of Approach Bridge of A Highway Bridge

根据某大桥引桥的结构特点,建立了空间动力计算模型,研究了结构动力特性;应用反应谱分析方法和非线性时程方法,研究了某特大桥引桥在E1和E2地震作用下的地震反应,并对E1和E2地震作用下的抗震性能进行了验算。

According to the structure characteristics of approach bridge of a bridge,the space dynamic calculation model was made and dynamic characteristics of the structure were studied;Seismic response of approach bridge of a grand bridge under the effect of E1 and E2 earthquake were studied with response spectrum analysis method and nonlinear time-history method and the seismic performance was checked.
