摘要
本文分析了珠江路立交桥B—B匝道桥台翼墙原设计的角度计算及台尾偏差问题，指出了设计中的不足，并以弦线代替曲线布置翼墙重新推导出了翼墙角度计算的通用公式．
The angle calculation and deviation of the original design on Zhu Jiang Roadovercrossing's B-B circumpath abutment wing wall are analysed in the paper,the deficiencyin design is pointed out and the general formula of calculating wing wall angle is recalculatedby way of string in place of curve to arrange wing wall.
