摘    要:在沉降观测过程中,获取的数据经常存在着不确定性,影响参数估计的可靠性和沉降预测的准确性。把不确定度作为参数融入AR模型,建立基于AR模型的不确定性平差模型。依据残差中不确定性传播规律,利用min-max估计准则,使得残差中的最大不确定度达到最小,从一个新的角度探讨不确定性观测数据的处理方法,得到基于不确定性算法的AR模型,扩展了现有误差理论。通过沉降实例进一步验证算法的优越性。

关 键 词:沉降观测  AR模型  不确定性

Abstract:Uncertainty often arises in the process of obtaining settlement observation data, affecting the reliability of parameter estimation and the accuracy of settlement prediction. This paper establishes a new adjustment model in which uncertainty is incorporated into the AR model as a parameter.An algorithm is given based on an uncertainty propagation law in the residual errors.A new way is used to research uncertainty, in which maximum possible uncertainty is minimized: existing error theory is extended with new observational data about uncertainty.
Keywords:settlement observation  AR model  uncertain
