| 摘 要： | 通过对沪宁公路南京东互通九座桥梁的研究，提出了连续箱梁的定位计算方法。该法为按设计先计算出桥梁轴线点和该点横断面上点的坐标及高程，然后进行箱梁的定位。运用此法可以：①确保公路线型和工程质量；②坐标、高程可在ＰＣ－Ｅ５００上编程设计；③桥梁和道路放样在桥头两端宜采用同一水准点和导线点。

| Abstract: | The eastern Nanjing interconnecting Bridges of the Shanghai-Nanjing Expressway are all on horixontal or vertical curves. The superstructure of these bridges is constructed with continuous box beams. In order to reach the required road alignment and guarantee the engineering quality the box beams were positioned through the points on the bridge centerline and the points on the cross section. This paper gives the method of coordinate and altitude computation of various points. The related error of computation is also discussed. |
