地下导线加测陀螺边最优位置确定及精度分析

Determination of Best Position of Observed Peg-top Azimuths at Underground Traverse and Accuracy Analysis

从熵的定义出发 ,运用熵变小准则导出了确定地下导线加测陀螺边最优位置的基本公式并用程序加以实现 .同时对测有多个陀螺方位角地下导线的平差及精度问题进行了深入探讨和分析 ,得出一些有益的结论 ,这对城市地铁建设中地下导线的布设和测量有一定的指导意义 .

This paper attempts based on the least entropy rule inferring the basic formulas,to determine the best position where observed peg-top azimuths were added to underground traverse using computer to realize the calculation.Moreover the adjustment system and the precision problem researched deeply while the observed peg-top azimuths were added to underground traverse making the conclusion of advantages of the calculation.This paper would benefit the construction of city subways for the arrangement and observation of underground traverses.
