全站仪参考弧在坑道测量中的应用

The Total Station Reference Arc Setting out Method Used in the Tunnel

在坑道施工中,坑道中弯道的放线通常采用传统的偏角法,但偏角法放样的流程较烦琐,且误差累积较大,而全站仪的参考弧程序可以很好地解决上述问题。坑道施工中,采用参考线(弧)放样快速准确地进行开挖、支护及被复的定位,可以提高效率,保证工期及质量。本文以徕卡TPS800全站仪参考弧程序为例,从参考弧的定义方法、使用方法等方面,对参考弧程序进行了探讨、分析,以起到抛砖引玉的作用。

During the construction of tunnel,the Setting out Method in the corner of the tunnel usually adopt the traditional Angle Method,but the process was complicated,and the error accumulation of more serious,Total Station Reference Arc can well solve the above problems. In the construction of the tunnel,the use of the Reference Line（ Arc） for the rapid and accurate excavation,support and the location of the recovery,improved the efficiency,guaranteed the construction period and the quality. Taking the Reference Arc procedure of the TPS800 Total Station as an example. This article discusses and analyzes the Reference Arc procedure from the definition and method of operation,to offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions.
