摘要
扬中二桥是位于长江夹江上的一座大桥,全长1755米,桥面宽17米,净高18米。由于桥中心线既有直线又有曲线,桥桩设计为群桩,设计单位仅提供桩中心坐标,层台及墩身四边平面坐标未能提供,施工中需另行计算。为了较核图纸桩位坐标;计算层台及墩身四边坐标,同时也为了今后遇到相关问题可以方便的解决,本文就这一问题提出分析;计算过程分:直线点坐标计算、缓和曲线段点位坐标计算、圆曲线段点位坐标计算、缓和曲线段外边点点位坐标计算。
The No. 2 Yangzhong Bridge is located on Jiajiang with the total length of 1775 meters, the deck width of 17 meters and the clear height of 18meters. Due to the bridge eenterline is both straight line and curve, the bridge pile are designed as pile groups. The design company only supplied the pile center coordinates except the coordinates of layer board and pier-body four sides which were need to calculate in construction progress. For checking the drawing pile position coordinates and calculating the coordinates of layer board and pier-body four sides expediently, the coordinate calculation method using EXCEL was introduced in the paper. Meanwhile it will supply an expedient solution method when encounters the related problems in the future. The calculation contents included the straight-line point coordinates, the gentle curve segment point-position coordinates, the circle curve segment point-position coordinates, the exterior boundary point-position coordinates of gentle curve segment and the exterior boundary point-position coordinates of circle curve segment.
