摘要
简述拟稳平差的基本原理,阐明在生产矿井控制测量中当起算数据不足时运用该原理进行控制网平差计算方法,通过对某生产矿井内起算数据不足的控制网进行模拟计算,说明该方法具有有效消除观测误差,提高平差精度的作用。
Introduces the basic principle of quasi_stable adjustment, explaining the method of control network adjustment using the principle when date data is not enough. Based on simulation of control network in mine when date data is not enough, knowing this method can eliminate effectively the observation error and improve precision of observation.
