摘要在传统的测量工作中,往往把平面控制测量和高程控制测量分开来。平面控制测量用的是导线测量的方法,高程控制测量用的是水准测量或者是三角高程测量。这样的作业方式没有充分地利用全站仪的坐标测量功能,没有充分发挥出全站仪的作用,减少了外业测量的效率。为了进一步提高测量工作的效率,并且充分利用好全站仪的功能,在实际外业测量过程当中,可以将外业观测数据的平面和高程同时观测,进行三维导线平差。78217
本文研究了三维导线测量的外业观测方法,在对导线平差理论研究的基础上,建立了相应的三维导线平差计算模型,以Visual Basic 6。0软件为开发平台,设计出三维导线平差计算程序,为图根控制测量作业提供参考依据。在输入原始数据后,能够直接显示平差的处理结果,并且用实例进行平差计算,比较和分析得出的结果,验证了该程序的正确性和可行性。

Abstract In the traditional measuring work, tends to separate the plane control survey and elevation control survey。 Plane control survey is the method of traverse survey, elevation control survey is leveling or trigonometric leveling。 Such practices not fully using the total station coordinate measuring function, did not give full play to the role of total station, reduce the efficiency of field measurement。 In order to further improve the efficiency of the measurement work, and make good use of total station function, in the actual process of field measurement and field observation data of the plane and elevation can be observed at the same time, 3 d wire adjustment。
This paper studies the method of three-dimensional traverse survey field observation, the wire adjustment on the basis of theoretical research, establish the corresponding three-dimensional traverse adjustment calculation model, with Visual Basic 6。0 software development platform, design the 3 d wire adjustment calculating program, to provide a reference basis for figure root control survey operations。 After the input raw data, processing results can directly show adjustment, and adjustment calculation by examples, the result of the comparison and analysis, validate the correctness and feasibility of the program。
Key words:Figure root control survey,three-dimensional traverse adjustment, Visual Basic 6。0
