Abstract:

归纳国内外已建和在建的桁架加劲悬索桥的一般情况,论述了加劲梁的受力特点,分析了主桁、横联、水平联和桥面的各可选型式的特点,根据统计数据得到了若干设计参数的经验取用规则。分析研究表明,在大跨度悬索桥中,抗扭能力是桥面结构最主要的加劲要求;加劲桁梁的高跨比与桥面设计风速的平方存在线性回归关系,因此可以由跨径和风速参数来初步拟定桁高;桥面设置一定透空是桁式加劲梁增进气动稳定性的有效和简便手段;上下平联采用K形撑比X形撑获得的扭转刚度要小,但K形撑不参与主桁竖弯,受力状态相对简单。对比混凝土桥面、钢桥面和合成型钢桥面3种方案的技术经济特点,合成钢桥面有助于提高加劲梁扭转性能和结构轻型化。
