摘要
大跨径悬索桥施工期尚未形成最终的结构体系,暂态结构的刚度较小,强风作用下的抗风安全性和舒适性已成为影响悬索桥安全顺利架设的关键问题。针对风荷载的特点及大跨径悬索桥施工期暂态结构的组成,分别对风荷载的模拟问题以及桥塔、猫道、缆索和加劲梁等施工期暂态结构抗风性能及控制的国内外研究现状进行了总结,同时提出了亟待解决的问题。
For the long-span suspension bridge under construction, the final structural system is not formed, their structural stiffness is greatly reduced, and the security and comfortableness of wind-resistant becomes important problems influencing the construction safety. For the behavior of the wind loading and the composition of the temporary structure,the advances of home and abroad research are reviewed, which is about the problem of the simulation for wind loading and the wind-resistant performance and control of the bridge pylon, catwalks, cables, stiff girder under construction of the long-span suspension bridge. Finally, some important problems regarding the wind-resistant research on long-span suspension bridge under construction are prospected.
