摘要
水文站点水准校测测量精度要求较高,应进行二等精度水准测量.采用先进的D iN i12数字水准仪结合铟瓦条码标尺对太湖流域浙江片水文站点进行观测,通过结合实践分析D iN i12数字水准仪的原理、性能和误差来源,叙述了二等精度水准数据处理过程以及精度评定.并通过对环境误差的遮挡幅度试验,得出了使用数字水准仪的方法和注意事项.
The standard calibration in hydrological stations asks for precision measuring,therefore,the second-class leveling is always carried out in order to ensure the measurement accuracy.The advanced digital level DiNi12,combined with indium-watt bar-code scale-plate,is adopted in hydrological station observations in zhejiang District,Taihu Basin.The principle,performance and error sources of digital level DiNi12 are analyzed based on the practice,and the data process of the second-class leveling and accuracy evaluation are also described in this paper.And the application and its relative regulations are concluded in the use of digital level after the block range test of environmental errors.
