一种改进的水准网条件平差算法

在实际工程应用中,水准网网形复杂多样,当进行平差时,间接平差未知参数个数选取要求高,条件平差方程建立不唯一,针对此类问题,本文提出了一种利用传递数矩阵建立条件方程的算法,判断水准网中的水准路线和水准点是否是已知值,依据传递数矩阵运算规则,确定条件平差中的系数矩阵和常数项矩阵,并利用2个算例进行分析比较,证明了所提算法的有效性。

An Improved Conditional Adjustment Algorithm for Leveling Network

In the application process of actual engineering,the leveling network is complex and diverse.When adjusting,the number of indirect adjustment unknown parameter selection requirements are high,and the conditional adjustment equation is not unique.For this kind of problem,this paper proposes an application The algorithm for establishing conditional equations by the transfer number matrix,according to the leveling route and leveling points in the leveling network,determine whether it is a known value,and determine the coefficient matrix and constant term matrix in the conditional adjustment based on the transfer number matrix calculation rules,and use 2 numerical example is analyzed and compared to prove the effectiveness of the proposed algorithm.
