Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, manual monitoring is used for deformation and settlement monitoring of subway tunnels, which is not conducive to comprehensive understanding and overall grasp of settlement deformation, resulting in certain potential safety hazards in the safe operation of subway tunnels. An online monitoring system and monitoring method based on subway tunnel deformation is proposed. Through online automatic monitoring and collection of tunnel differential settlement data information, and automatic analysis and calculation of tunnel differential settlement data information, online deformation monitoring and safety assessment of subway tunnels can be realized, and subway tunnels can be effectively guaranteed. Safe Operation of the Tunnel

Abstract

The invention relates to an online monitoring system and monitoring method for subway tunnel deformation. The monitoring system comprises a data information collecting subsystem, a data communication subsystem, a data collecting and analyzing subsystem and a monitoring alarming subsystem. The monitoring system is used for realizing real-time online collection of the data information of subway tunnel deformation, performing centralized analysis treatment on the collected data information of subway tunnel deformation under the current condition of a subway tunnel and performing early warning and alarming. The online monitoring for subway operation safety is realized on the basis of technology of the Internet of Things. The online monitoring system has the advantages of simple structure, low cost, labor saving, complete data collection, high efficiency, humanization, intelligence, and the like.

Description

technical field [0001] The invention relates to the field of subway tunnel safety monitoring, in particular to an online deformation monitoring system and a monitoring method of a subway tunnel. Background technique [0002] The operation of subway tunnels has greatly relieved the pressure on urban traffic and brought convenience to people’s daily travel. However, subway tunnels are easily affected by different factors. For example, subway tunnels often pass through bad geological areas (backfill areas, quicksand layers, mining empty area, soft rock section and fault zone, etc.), the vibration load during the operation of the train will activate the unfavorable geological area, thereby causing the track to deform; for example, other line construction and other external loads such as new buildings will The subway tunnel lines that have been in operation have adverse effects. These influencing factors will cause deformation, inclination, displacement, uplift or settlement of t...
