摘　　要：为了削弱短程红外测距仪系统误差——固定误差——对城市和工程测边网(包括导线网和边角网)的影响,本文提出了一种设立固定误差因子的平差方法,导出了设立固定误差因子的测边网间接平差和条件平差的有关公式,并提出了一种比传统的方法更为合理的解算方法。最后,对附合单导线设立固定误差因子的条件平差法,做了一个算例。计算结果表明,设立固定误差因子的平差法,可以有效地消除短程红外测距仪固定误差对边长测定的影响,从而可以进一步地提高城市和工程测边网的质量。In order to weaken the effect of the systematic error (constant error) of the shortrange infrared distancemeter in the trilateration network of city and engineering surveying (including traverse network and trilateration/triangulation network), this paper presents an adjustment method establishing the constant error factor. The relative formulas of the adjustment of condition equations and indirect observations are derived. A more reasonable solution method is put forward. Final, an example for adjustment a single traverse is given.The results show that establishing constant error factor adljustment method will be effectively able to eliminate the constant error of surving range by the infrared distancemeter. The quality of control network of city and engineering surveying will be improved.
