摘要
在实施变形监测的过程中,两期变形点坐标值的差异并不一定反映点位的变动,它也可能是测量误差引起的;为探明这些差异主要是误差干扰还是变形造成的位移,需要进行位移量显著性检验;文章在误差椭圆法进行点位变形分析的基础上,提出了误差椭球法进行点位位移量显著性分析,该方法适用于三维坐标变形分析的问题,并用一组数据进行了验证。
In the process of deformation measurement, the coordinate differences between two terms do not always mean deformation for sometimes they are caused by error of measurement. In order to investigate what is the reason of the differences, the significance analysis of displacement should be carried out. A method of using the error ellipsoid to analyze the significance of displacement of points is presented based on the error ellipse method which is used to analyze plane points deformation. This method can be applied to the problem of three-dimensional deformation analysis. A calculation example is given.
