数字水准仪在二等水准测量中的误差来源及分析

Research on the Error Source of Second-Class Leveling and its Solution

二等水准测量属于精密水准测量,其精度要求高,在施测过程中,应对误差进行严格控制。文章结合使用数字水准仪进行二等水准测量的测算实例,逐层分析了误差来源,并提出相应的误差控制措施。

Second-class leveling is a kind of precision leveling,which requires high precision.The error should be strictly controlled in the process of measurement.In connection with the calculation of the second level measurement by using a digital level gauge,the source of error was analyzed by layer and the corresponding error control measures were put forward.
