全自动陀螺全站仪施工现场校准比对施工技术

Construction Technology About Field Calibration Comparison of Automatic Gyroscope Full-Station Instrument

通过实践应用总结出陀螺全站仪现场校准比对技术。在隧道使用现场状态下对陀螺全站仪的稳定性、内符合精度、外符合精度、陀螺仪与全站仪同轴度、仪器常数测定等方面进行测试,评价陀螺全站仪的综合性能精度。对现场检测校准陀螺全站仪具有重要的实践意义,并为今后制定陀螺全站仪校准规程提供参考。

Based on the practice application, the field calibration comparison technology of gyroscope full-station instrument is summarized. At the scene of the tunnel, the stability of the gyroscope full-station instrument, the internal coincidence accuracy, the external coincidence accuracy, gyroscope with full-station instrument coaxiality and the instrument constant measurement are tested, so as to evaluate the comprehensive performance precision. This technique has important practical significance for the field detection and calibration of full-station instrument, which could provide a reference for the calibration standards of full-station instrument.
