| Abstract: | 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. |
