摘要:
我国高铁桥梁建设发展迅猛,其中一大批桥梁处于强台风多发区,其抗风性能备受重视,高铁桥梁的主梁断面静力三分力系数分析是其抗风研究的基础。本文基于计算流体动力学(CFD)技术,对东南沿海某大跨度高铁连续梁桥箱梁断面静力三分力系数开展研究,考虑不同风攻角和主梁断面尺寸对静力三分力系数的影响,并将识别结果与已有数值计算结果进行对比。结果表明:采用CFD技术可有效识别高铁连续梁桥钝体箱梁断面静力三分力系数,箱梁断面尺寸的变化对静力三分力系数影响显著。随着断面高宽比的增大,箱梁断面的阻力系数和升力系数也随之增大,而升力矩系数随之减小。研究结论可为大跨度高铁连续梁桥的抗风研究与设计提供有益参考。
Abstract:
The construction of high-speed railway bridges in China has exhibited a rapid development recently. A large number of bridges are located in strong typhoon-prone areas, and the wind-resistance performance has drawn much attention. The study of static tri-component coefficients of the main beam section of high-speed railway bridge is the basis for the wind-resistant design of bridges. Based on computation fluid dynamics(CFD), the static tri-component coefficients of some typical sections were analyzed in this paper. The sections were selected from the main beam of a large-span high-speed railway bridge on the eastern coast. The influences of wind attack angle and section height were also taken into consideration. The comparison between the recognition results and existing ones proved that the utilization of CFD to simulate the static tri-component force coefficients retained high feasibility and reliability. The dimensional variation of the bridge section had a significant influence on its static tri-component force coefficient. As the height of the section and the angle of attack of wind increased, the drag coefficient and lift coefficient of the bridge section also increased, meanwhile the coefficient of lift torque decreased. The conclusions can provide useful reference for the wind resistance design of long-span high-speed railway continuous beam bridges.
