Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] figure 1 It shows that Embodiment 1 of the present invention provides a method for early warning of tunnel surrounding rock deformation, including:

[0036] S11. Layout monitoring points at preset positions of the tunnel. In this step, it should be noted that tunnels can be classified into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and so on. The monitoring at the vault mainly monitors the sinking of the vault, and the monitoring at the waist of the vault mainly monitors the surrounding convergence. Detection devices shall be installed at the monitoring points to collect data information on the deformation of the surrounding rock of the ...

Abstract

The invention provides a tunnel surrounding rock deformation early-warning method and system. The method comprises the steps that a monitoring point is arranged at the preset position of a tunnel; a collection terminal obtains data information of the monitoring point and obtains deformation information according to the data information; when it is determined that the deformation information is larger than a preset threshold value, the deformation information and warning information are sent to a service side, so that the service side displays the deformation information and sends warning information to other receiving devices. According to the tunnel surrounding rock deformation early-warning method, data information of an arch crown or waist is obtained in real time through the collection terminal, the data information is analyzed to obtain deformation information, the deformation information is compared with preset information, and therefore whether warning information is sent while the deformation information is sent to the service side is determined. By means of the method and system, data collection, data analysis and situation warning can be achieved, corresponding measures are taken in time according to judgment on the warning information, tunnel surrounding rock management is enhanced, and follow-up engineering construction safety is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel surrounding rock early warning, in particular to a tunnel surrounding rock deformation early warning method and system. Background technique [0002] With the construction of a large number of tunnel projects, more and more attention has been paid to the risk monitoring of tunnels, especially the excavation of tunnels in high-risk geological sections. Under the condition of mastering the progress of the project, the engineering unit hopes to discover the risks in time and take necessary measures to reduce the construction cost, and then guide the construction. Tunnel monitoring and measurement not only needs to meet the needs of construction and management of engineering units, but also needs to quickly establish an early warning mechanism through information technology, notify the construction unit in a timely manner, establish and improve the risk management supervision mechanism and closed-loop ...
