全站仪三角高程测量代替三四等水准测量分析研究

Total Station Trigonometric Leveling to Replace the Three or Four Leveling of Feasibility Analysis

以三角高程测量原理为依托,依据全站仪三角高程测量中单向和中间法的测量模式,确定不同作业方式中的误差来源,利用误差传播定律确定各种误差在整体误差中的权重.通过精度分析总结在已有的设备条件下,采用单向观测和中间法作业方法,确定在怎样的作业条件下能够代替三四等水准测量.

Replying the total station trigonometric leveling and basing on the unidirectional method of the total station trigonometric leveling,we can determine the practices in different sources of error and make use of the weight during the all error of the error propagation law.Through the analysis of precision,we can summarize under the existing equipment conditions,respectively under the condition of the middle and the intermediate method,we can also determine when we can use the trigonometric leveling method substituting the three or four leveling under same conditions.
