摘要
对于建筑物的垂直变形观测，粗差的存在必将严重改变垂直变形信息，影响垂直变形分析结果的可靠性，因此，粗差的定位和剔除极为重要。用单个粗差的向前、向后探测法，对粗差进行检测，连续结合使用上述两种方法可对多个粗差进行数据探测，可以发现建筑物实际的垂直变形。此方法对多个粗差的定位和剔除有效，可以提高垂直变形观测的可靠性。在粗差探测时。
In observation of vertical distortion, the existence of gross error will change the real information about the vertical distortion, which may degrade the reliability of vertical distortion analysis. Hence it is very important to determine and remove gross error. Back and forward single snooping methods are used to detect gross error respectively or the two methods are combined to detect the multi gross errors. The calculation of examples show that this method can improve the reliability of observation results of vertical distortion.
