摘要
在利用无砟轨道铺设时建立的CPⅢ控制网点,用全站仪自由设站后方边角交会进行轨道精调测量。以全站仪自由设站后方边角交会的斜距、水平方向和天顶距为观测量,推导了自由设站严密平差计算的数学模型,确定全站仪中心三维坐标的测量原理,数据处理和实现方法。并使用(Embedded VisualC++)EVC4.0+SP2结合TOPCON GTS内部通讯接口进行了系统的编程实现。
Track adjustment measurement of high-railway is done in this paper by the method of free stationing with the points of CP III around the ballastless track. Building strict adjustment model of free stationing, computing the of total station, and data processing are researched on the base of slope-distance, horizontal direction and zenith angle as observations collected by freestationing. The model is realized through Embedded Visual C＋＋ on TOPCON GTS.
