摘　　要：南京长江第三大桥索塔采用钢结构属国内首创,采用这一新型的建桥技术,对施工测量提出了更高的要求,也给出了一系列新的探索课题。本文以该桥工程建设实例,介绍了钢塔节段制作和架设施工过程中的测量方法及其精度控制措施。实践证明,所采取的测控方法科学、合理,是精密工程测量的一次成功尝试,可为今后类似工程借鉴。The main bridge of No.3 Nanjing Yangtze River Bridge is a steel pylon cable stayed bridge. This kind of steel pylon is originated in China. Its new technique requests a higher construction surveying and gives a series of new tasks to survey controlling. This paper, taking this bridge project as an example, introduced the measurement methods and the controlling measures for making and erecting the steel pylons. The practice has verified that the survey controlling methods used in this project is scientific and reasonable. It is a successful trial of precise engineering survey and very instructive for similar project.
