摘要
在特长隧道的控制测量中,为提高精度,采用平差计算法以实测值确定观测值权,使平差计算结果更符合实际情况,该方法常利用自编的表格计算程序进行,可极大地提高计算效率,减轻工作强度,提高计算精度和成果的高可靠性。
In order to improve the precision, it often applies the practical value of ajustment algorithm to ascertain the weight observation value during the controlling measurement of super-long tunnel. This method uses table program can improve greatly the efficiency and precision of calculation, and reduce the work strength, with high reliability of calculation result fitting for practical condition.
