| 摘 要： | 通过对全站仪中间法三角高程测量原理进行分析,推导了中间法三角高程的误差传播公式,研究了测距误差、测角误差和大气折光系数误差对高差的精度影响。采用中间法三角高程测量方法在一个较小范围内进行了三角高程测量,779 m的水准路线测量闭合差为0.5 mm,并和精密二等水准成果进行了对比分析,试验结果验证了该方法可以替代高精度水准测量的可行性。

| Abstract: | Based on the analysis of trigonometric leveling principle of total station using midway method,error propagation formula is derived for this method. On the basis of the formula,the elements including distance error,angle error and atmospheric refraction coefficient are studied to analyze the impact on the height difference errors.After that,a test is carried out in a smaller range using midway method of triangulated height. In addition,the route of the test is 779 m and the closing error is 0. 5 mm. A comparison of the test results with precision secondlevel outcomes is analyzed,the analysis verify the feasibility that the method can replace the high-precision leveling. |
