摘要
以某半径为240m的四跨连续曲梁为例,分析了独柱墩支座不同的预偏心对连续曲梁扭矩分布以及支撑反力的影响,介绍了通过调整支座的预偏心设置来改善曲梁扭矩的分布,以优化结构受力。
Take the four- span continuous curved girder （Radius： 240m） as an example, the influences of different pre - eccentrics of single bearing to the distribution of continuous curved - girder are analyzed. The methods to adjust the pre -eccentric of bearings to improve curved- girder torsional moment distribution are analyzed, so that the bearing capacity of the structure can be optimized.
