摘要
以间接平差理论为基础,建立了导线平差的数学模型,并对导线的一般形式进行了探讨.考虑到导线可能以GPS点为起算点构成无定向导线,同时,无定向导线也适用于附和导线和闭合导线,因此,以无定向导线为基础,使导线间接平差数学模型更具普遍意义.建立导线间接平差数学模型的过程与导线的实际计算步骤完全一致,这样对手工计算和程序设计都很方便.同时,在公式中,依据导线的点数N,提供了详细且严密的下标通式和下标界,因此,笔者所提供的导线间接平差数学模型充分体现了实用性和通用性.
Based on the theory of parameter adiustment, the mathematical model of traverse adjustment is created in this paper, and the general forms of traverse are discussed. Mathematical model of traverse parameter adjustment based on nondirective traverse is widely used considering nondirective traverse not only suits for traverse using point of GPS as start one, but also for connecting traverse and closed traverse. It is very convenient for manual calculation and program design because the procedure to create mathematical model of traverse parameter adjustment is closely corresponded with the actual calculation. At the same time, strict formula of suffix and limit of suffix are provided based on the number of traverse points. So mathematical model of traverse parameter adjustment mentioned in this paper is practical and generally used.
