摘要
以重庆鱼嘴长江特大桥为研究对象,建立了空间有限元模型,进行了成桥阶段的特征值分析、动力荷载时程分析及地震反应分析,研究了车速对桥梁动力反应的影响。
Taking Chongqing Yuzui the Yangtze River Bridge as investigated subject its spatial finite element model is built. Eigenvalue analysis, time history analysis of dynamic load and seismic response analysis of the bridge in finished phase are made. In the end the impacts of vehicle speed on dynamic response of bridge are studied.
