南昌大桥桥墩抗浮运管段撞击能力评估及复合材料防撞设计
Assessment of resistance to floating pipe impact capability and protection method of Nanchang Bridge piers
摘要
Abstract
The internal forces of the most dangerous section of Nanchang Bridge pier under the horizontal impact force were calculated.According to the relevant design code,the ultimate lateral bearing capacity of the bridge pier was calculated.Considering the effects of impact angle and the fortified water level,finite element software ANSYS/LS-DYNA modeling was used to analyze the impact force of piers impacted by floating pipes.The calculation results indicate that the ship impact forces of the piers are obviously more than the resistance forces,whatever the piers were crashed by transverse or along to the bridge.According to the characteristic of the water where the bridge located and the ability of the resistance to ship impact of the piers,a soft composite anti-collision facility was designed to satisfy the fortification requirements of the main piers.关键词
