摘要
本文建立了参数样条变形模型，同时考虑三个方向随时间变化的变形规律。建立动态整体变形模型，分析变形区内各测点的变形情况。并且考虑了外界环境多因素对垂直方向的影响。为了在一定程度上减小观测误差对模型的影响，又提出了在逼近度量和光滑度量同时限制下的样条参数估计方法。
This paper describes a deformation model of parameter spline in which the time-
varying deformation regularities in 3-dimension are taken into account. An overall dynam-
ic deformation model describing the deformation of each observing station in the
deformation zone is also established. the effects of various ambient factors on vertical
direction have been considered in the model. In an attempt to reduce the effect of obser-
vation error on the model to some extent. a spline parameter estimation method subject
to the constraints of both approximation and smothing measures is proposed.
