导线测量是地下空间控制测量的常用手段，但当地下导线超长过多时，常规导线测量难以达到精度要求。陀螺全站仪的使用是一种有效手段。本文以济南市地下人防工程干道测量为例，介绍在地下超长导线测量中多次加测陀螺方位角的作业流程，给出了加测N个陀螺方位角的考虑因素，并对加测陀螺方位角前后的成果进行了对比分析。结果表明：在导线超长时，通过多次加测陀螺方位角的方法，可以保证导线测量精度满足规范要求。
導線測量是地下空間控製測量的常用手段，但噹地下導線超長過多時，常規導線測量難以達到精度要求。陀螺全站儀的使用是一種有效手段。本文以濟南市地下人防工程榦道測量為例，介紹在地下超長導線測量中多次加測陀螺方位角的作業流程，給齣瞭加測N箇陀螺方位角的攷慮因素，併對加測陀螺方位角前後的成果進行瞭對比分析。結果錶明：在導線超長時，通過多次加測陀螺方位角的方法，可以保證導線測量精度滿足規範要求。

Traverse survey is a common method of underground space control measure , but when the underground traverse long too much ,it is difficult to achieve the accuracy requirement of conventional traverse survey .The use of gyro is an effective methods .This paper takes the underground civil air defense projects in Ji'nan city road measurement as an example ,introduces several adding measuring gyroscope azimuth angle operation process in ultra long underground trav -erse survey ,gives added measure factors into N gyroscope azimuth angle ,and the added gyro azimuth measurement results are analyzed contrastively before and after .The results show that: in the lead long , through many added gyro azimuth measuring method ,can guarantee the precision of traverse measurement and meet the specification requirements .
