泉州后渚大桥防撞岛结构试验与分析研究

Testing and analytical study on anti-collision island of Houzhu Bridge of Quanzhou

以泉州后渚大桥防撞岛为工程背景,通过船撞模拟试验和非线性有限元分析,研究了船舶撞击防撞岛时的船撞力及防撞岛内部的应力分布和变形.试验和计算分析结果表明,设计船撞力超过设计预期的经验值30%以上,但防撞岛在船舶撞击下的破坏模式与设计预期的基本一致.

Based on a practical engineering of Houzhu Bridge of Quanzhou, the force of ship collisions with anti-collision island and its internal stress distribution and deformation are studied by model testing and nonlinear FEM analysis. The testing results show that the design ship collision force is about 30 percent higher than the experiential value expected. The results of FEM analysis show the damage mode of the anti-collision island is in good accordance with the one expected.
