| 摘 要： | 基于随机振动理论，考虑了地震动空间效应，对一座主跨240米自锚式混凝土悬索桥在多支承激励下进行了地震反应分析，以及在地震波的三向正交分量独立作用和联合作用下的地震反应进行了数值计算，探讨了行波效应和部分相干效应对自锚式悬索桥地震反应的影响．

| Abstract: | Based on random vibration theory, by taking into account the seismic action with spatial variation, the earthquake response of a self-anchored suspension bridge with center span of 240m to multiple-support excitations is investigated, and numerical calculation is presented for seismic response subjected to independent effect or combination effect of three orthogonal components of seismic wave. The seismic response of self-anchored suspension bridge by considering traveling effect and correlated effect is discussed in detail. |
