This paper deeply studies the measurement technology of the long subway tunnel control network and its error analysis in the penetration measurement,pays special attention to the complexity of the above-ground and underground coordinate transmission and its influence on the measurement accuracy,discusses the error source in the measurement of the subway tunnel control network through the in-depth analysis of the actual case,and proposes the corresponding error control strategies and solutions.In addition,the article also discusses the application of new measurement techniques in practical engineering,provides effective guidance and promotion value for similar projects.
