剔除变形监测粗差数据的新方法——数据跳跃法

当观测值中有多个粗差时拉依达法则一次只能剔除一个粗差,并且多个粗差之间互差不满足一定条件时拉依达法则失效.针对此问题在拉依达法则基础上提出了一种剔除变形监测粗差数据的新方法数据跳跃法.数据跳跃法克服了拉依达法则的部分局限性,可将含有粗差的变形监测值批量剔除,为一次剔除多个粗差提供了解决方法.采用该方法对实际监测数据进行了处理,取得了较好的效果.数据跳跃法为利用程序进行粗差判定与剔除提供了理论依据和算法.

Data Jump Method:a New Approach to Eliminating the Deformation Monitoring Data with Gross Errors

When there are several gross errors in the observations,the Pau Ta's criterion can only eliminate one at a time.If the mutual deviations among the gross errors do not satisfy certain conditions,the Pau Ta's criterion will be invalid.To solve this problem,a new approach named as data jump method based on the Pau Ta's criterion was proposed.It overcomes the limitation of the Pau Ta's criterion.The deformation monitoring data with gross errors can be eliminated in batches.The method is used to process some act...
