摘要
针对高墩大跨连续刚构桥悬臂浇筑过程中稳定性差的问题,研究了西北沟谷地形风场基本风速推算方法,采用动力荷载模拟结构在风作用下结构动力响应,并基于Diekemann的舒适度评价方法分析了施工人员的舒适性,提出了此类桥悬臂施工的适宜风速范围。
According to poor stability of high pier and large span continuous rigid frame bridge cantilever casting process problems, studies the calculation method of the Northwest valley terrain wind field basic wind speed, by using dynamic load simulation structure in structural dynamic response under the action of wind, using Diekemann comfort evaluation method based on the analysis of the construction personnel comfort, put forward suitable wind speed the scope of this kind of bridge cantilever construction.
