摘要:浮式柔性多级消能桥船防撞结构因其消能效果好、便于养护维修等优点逐渐成为水运桥防撞装置的主要选择结构之一。本文采用有限元方法,对某桥的浮式转动消能防撞结构进行了不同撞击位置和角度下的多种工况碰撞仿真模拟。结果表明:个别桩基础混凝土会发生压应力破坏,而钢套筒均没有失效,整体结构仍具备一定防撞能力。该项研究为桥船防撞结构设计与优化提供了参考。
Abstract: The bridge-ship anti-colision structure of floating flexible muli-stage enery dissipation has gradually become one of themain choice structures for the anti-collision device of water transport bridge because of its good energy dissipation effect and easymaintenance. In this paper, the finite element method is used to sinmulate the collision of a floating rotating energy dissipation anti-collisionstructure of a bhridge under diferent impact positions and angles. The results show that under various impact conditions, compressive stressfailure will occur at individual positions of concrete,while the steel sleeve will not fail, and the overall structure still has certain anti-collision ability.This study can provide a reference for the design and optimization of bridge-ship anti-collision structure.
