In the urban rail transit engineering, the construction of undercutting under the existing rail line is plagued by high construction risk and high monitoring accuracy requirements. Taking a station A in an urban rail transit project as an example, combined with the characteristics of the project, the monitoring scheme of vault settlement in the excavation section is formulated. In order to establish two sets of relatively independent elevation system and adopt the method of setting up independent station to measure the inverted ruler, the feasibility of this method is verified, and the sources of measurement error and control measures are analyzed. The actual results show that the method can meet the requirements of monitoring accuracy of vault settlement in the underground excavation section of subway station.
