摘要
变形监测中,可能同时存在粗差和变形两类模型误差,常用的方法是从可区分性理论出发,研究监测网发现粗差并与变形相区分的能力。针对三维变形观测一类问题,提出坐标位移模型,以此将变形与粗差相分离,并直接在模型中发现粗差,提高了观测系统的可靠性。
n the monitoring deformation, it is possible to exist two kinds of model errors at the same time. In general, the used method is, with the help of the theory of seperablity, studying the ability of monitoring network which tests gross errors and also divorces gross errors from deformation. Being aimed at one kind problem of three--dimensional deformation monitor, this paper puts forword the coordinate displacement model. By the model, deformation and gross errors are divorced 1 and the reliablity of the surveying system is enhanced.
