| 摘 要： | 本文以跨浅海水道连续桥为研究时象,采用质量弹簧体系模拟基础和地基,用有限元通用软件分别建立了该桥的考虑桩-土-结构作用的全桩模型、将基岩中桩截去且考虑桩-土-结构相互作用的截桩模型和不考虑桩-土相互作用的无桩三维有限元模型。以此为基础,对该桥进行三维地震动态时程分析,分析了桩-土-结构相互作用对该桥动力特性的影响和不同地震动输入下桩-土-结构相互作用对该桥位移反应、内力反应等地震响应的影响。

| Abstract: | This paper studies continuous bridge spanning shallow sea channel.The mass-spring system was used to simulate foundation and subgrade;the finite element common software was used to build the whole-pile model considering pile-soil-structure interaction,the incomplete-pile model considering pile-soil-structure interaction with cutting out the pile in the original rock,the three-dimensional finite element model without considering pile-soil interaction.It also studies three-dimensional earthquake dynamic time history analysis,and analyses the influence of pile- soil-structure interaction on the dynamic property,the influence of pile-soil-structure interaction at different earthquake simulation on the reflection of displacement and internal force. |
