摘要： 介绍了全站仪三角高程法在田林路下穿中环地道新建工程中环路面沉降观测中的应用情况，并对三角高程测量中误差进行了估算，定期利用中环路面养护的条件采用几何水准测量对三角高程观测成果进行验证比对，成果相差较小，为类似难以采用自动化观测及几何水准测量方法的工程提供一定的参考经验。

Abstract: This paper introduces the application of the total station triangulation method in the ground settlement observation in the excavation of an under passing tunnel at Tianlin Road project. The error in the elevation survey was estimated. The frequent comparisons of elevation results observed from geometric level method and from triangulation method resulted a reliable conclusion that the triangulation method is acceptable in the ground settlement observation.

Key words: total station triangulation method, geometric level, settlement observation, steel pipe pile wall
