大跨弯坡高刚架桥施工控制分析

Analysis of long span curved high rigid-frame bridge construction control

介绍自适应控制原理在桥梁工程中的应用。采用结构空间受力分析与工程试验、现场实测相结合的方式 ,通过对大跨曲线梁桥挠度控制影响因素的分析 ,重点阐述了扭转预拱度的设置及桥墩变形对扭转效应的影响 ,并对施工及设计提出一些建议。

This paper introduces the application of self adaptive control on engineering. The influence factors of long span curved girder bridge deflection control are analyzed by the means of combining space analysis with engineering test and construction site survey. The torsion counter camber setting and the influence of bridge pier deformation on torsion effect are elucidated primarily and some advice is given for construction and design.
