| 摘 要： | 以某大桥主桥桥墩为工程背景,模拟分析桥墩在遭遇船舶撞击作用下,经过船舶撞击、管桩连接系、钢吊箱围堰、塔吊传递、承台及桩基的消能转化后桥墩结构的响应(应力、位移),模拟结构的模态参数(频率和振型),结合实测结果,对桥墩结构消能状态进行评估,为桥墩防撞事故分析提供参考。

| Abstract: | Taking main bridge pier of a bridge as background,this paper simulates and analyses the structure responses(stress,displacement)of the bridge pier which are weakened by ship impact,pipe pile connection system,steel suspending cofferdam,tower crane transmission,the cap and pile foundation.This paper simulates and analyses the modal parameter(frequency,vibration mode),evaluates the structural energy dissipating behavior of the bridge pier also combining measured results.The research could provide reference to... |
