【摘要】 以厦门海沧大桥西航道桥(五跨预应力曲线连续刚构,曲率半径900m)为工程背景,对该桥分别进行了不同曲率半径、不同地震波激励方向的分析。通过该桥地震响应分析,给出了一些地震响应规律以及分析建议,期望能为新规范的制订工作以及高墩大跨曲线连续刚构桥的抗震设计提供参考。更多还原

【Abstract】 Taking western approach bridge of Xiamen Haicang Bridge (PC and curved continuous rigid frame of five spans,with 900m curvature radius)as project background,the paper carries out the seismic response analysis of the bridge.Based on the seismic response analysis of the bridge,some conclusions and suggestions are given out,whith are expected to provide the theory basis for establishment of the new seismic code and the seismic design for the curved continuous rigid frame bridges with high piers and long span.更多还原
