高差闭合差超限问题分析

Analysis on exceeding problem of height difference closed difference

采用理论分析与现场测量的方法,从仪器误差、水准点高程变动、观测误差等方面,分析了高差闭合差超限的影响因素,并针对具体的影响因素,提出了解决措施,以消除误差,解决超限问题。

This paper used the theoretical analysis and field measurement method,from the instrument error,benchmark elevation change,observation error and other aspects,analyzed the influence factors of height difference closed difference,and according to specific influence factors,put forward solved measures,in order to eliminate the exceeding problem.
