谈贵州北盘江特大桥索道管的施工定位

摘要

结合贵州北盘江特大桥索道管施工定位的现场实践，对北盘江特大桥索道管定位进行了分析，从理论原理定位与实际操作定位进行了论述，提出了利用函数方程式及三维极坐标的定位方法，进行索道管定位的研究，达到了理论数据与实际数据拟合较好的效果，解决了索道管定位现场出现的一些问题。%Combining the practice in Guizhou Beipan River Bridge cable duct’s construction and positioning,we made analysis about Beipan River Bridge cable duct’s positioning,discussed the positioning between the theoretical principles and practical operations,proposed the use of the function equation and three-dimensional polar coordinates positioning method,and studied the positioning of cable duct,thus reaching a rela-tively good fitting effect between the theoretical data and actual data and solving some problems occurred in the scene of the cable duct positioning.
