Tunnel section deformation monitoring system and monitoring method

Abstract

The invention discloses a tunnel section deformation monitoring system. The system comprises a main controller and a plurality of sub-monitoring devices arranged in a tunnel. The main controller is communicated with a mainframe, and the sub-monitoring devices are arranged in the length direction of the tunnel and include sub-controllers communicated with the main controller, first laser range finding sensors, second laser range finding sensors and memories. The invention also discloses a tunnel section deformation monitoring method. A settlement value of a tunnel vault, a convergence value ofthe tunnel vault and a convergence value of a tunnel haunch are calculated through the sub-controllers and then correspondingly transformed into a tunnel settlement language evaluation value, a tunnelvault convergence language evaluation value and a tunnel sidewall convergence language evaluation value, and an early warning can be provided for construction to help work staff to understand the tunnel security situation in real time and check existing potential security risks in advance.

Description

technical field [0001] The invention belongs to the technical field of tunnel monitoring, and in particular relates to a tunnel section deformation monitoring system and a monitoring method. Background technique [0002] my country began to analyze and study tunnel safety monitoring in the 1980s. At the beginning of 1988, Southwest Jiaotong University and Guangzhou Highway Bureau jointly studied and formulated the "Interim Regulations on the Safety Grade Assessment of Highway Operation Tunnel Lining", which was used as the guiding specification for tunnel safety monitoring. In terms of engineering monitoring, in recent years, the method of manual detection is mainly adopted. Monitoring personnel regularly measure the key points of the tunnel through testing instruments such as total stations, levels, and convergence rulers, and report the obtained data to the tunnel management department. The tunnel management department organizes experts to conduct regular analysis on the ...

AI Technical Summary

Problems solved by technology

At present, domestic measurement of tunnel vault settlement mainly uses instruments such as total stations, levels, and 3D laser scanners, which require multiple manual measurements and cannot be automated.

At present, there is no complete solution for the monitoring of relevant dangerous tunnels at home and abroad. The monitoring of relevant tunnels requires long-term theoretical analysis and on-site engineering exploration. , so that the tunnel hazard cannot be dealt with in time
