大湾特大桥自振特性分析

摘要

The 3D finite element model of Dawan Bridge is established based on large-scale general-purpose finite element programs and the natural vibration frequencies and types of the structure of the bridge are calculated,whose results will be of value of parameter references for the testing and maintenance in design,construction and use.%利用大型通用有限元程序建立了大湾特大桥的三维空间有限元模型,计算了该桥梁结构的自振频率和振型,计算结果可为该桥的设计、施工以及使用阶段的健康检测和维护提供技术参数和依据。
