Operation subway station deformation monitoring method

Abstract

The invention relates to the technical field of subway safety, in particular to an operation subway station deformation monitoring method. According to the technical scheme, prisms are arranged at a datum point and a measuring point in a station tunnel according to monitoring specifications and a subway management method, and a total station is arranged at a set station; after the arrangement is finished, an initial value of a monitoring project is measured through the total station; after construction is started, real-time measurement is conducted through the total station to obtain a monitoring project actual measurement value, and the monitoring project actual measurement value is compared with the monitoring project initial value; and comparison results are graded and the results are fed back to a responsible unit. The deformation trend and the deformation amount of the subway tunnel during road construction can be monitored in real time, the deformation rule and characteristics ofthe tunnel are mastered, and data support is provided for guaranteeing subway safety.

Description

technical field [0001] The invention relates to the technical field of subway safety, in particular to a method for monitoring the displacement of an operating subway station. Background technique [0002] With the rapid development of the urbanization process, urban subways have also been developed at a high speed. There are subways underground in existing large and medium-sized cities, and the subways often pass through the old urban areas. However, with the development and construction of the area and the opening of the subway, the original roads can no longer meet the transportation needs of the area. It is necessary to sort out the road network of the area according to the new plan and renovate the original roads, such as: [0003] Huiwangling Station and adjacent sections of Chengdu Metro Line 2 have been officially put into operation. Huiwangling Station is an island-style station with two floors underground. It adopts open-cut construction. The current roof covering...

Problems solved by technology

[0005] That is to say, the Yuzhu Road Subway is safely adjacent to Subway Line 2 and is located within the scope of protection of the Subway. During the construction period of the project, Subway Line 2 stations may experience settlement, floating, and lateral displacement. When the deformation reaches a certain When the level is high, the station structure will be misaligned, cracked, etc., which will affect the structural safety of the tunnel.

However, when the station is in operation at present, it is almost impossible to perform manual monitoring in the station with a large flow of people and on the track bed where the subway runs intensively.
