Tunnel sounding rock pressure monitoring and pre-warning system

Abstract

The invention discloses a tunnel sounding rock pressure monitoring and pre-warning system. The tunnel sounding rock pressure monitoring and pre-warning system comprises a collecting device, a server,a display device, a pre-warning device and a post-processing device. The collecting device, the display device and the pre-warning device are connected with the server. The post-processing device is connected with the pre-warning device. The tunnel sounding rock pressure monitoring and pre-warning system is capable of realizing a process from the data collection, the data analysis, the informationdisplay and the situation alarm to a step of starting advanced safety precaution. The pre-warning device is capable of identifying pre-warning information sent by the server and sending an alarm in the corresponding level. The level of the alarm is generated according to the comprehensive identification of the close time of the tunnel damage, the loss after the damage and the hazard degree, and the post-processing device is capable of adopting the relative measures in time according to the identification of the pre-warning information, reinforcing the management of the tunnel surrounding rock, and guaranteeing the safe operation of a subsequent project.

Description

technical field [0001] The invention relates to the technical field of tunnel surrounding rock monitoring and early warning, in particular to a tunnel surrounding rock pressure monitoring and early warning 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 in areas with frequent geological activities. In order to monitor the tunnel sections with high importance and high possibility of damage at any time, to ensure the safety of the tunnel in the later stage Operation, tunnel monitoring and measurement not only need to meet the needs of engineering units for construction and post-management, but also need to quickly establish an early warning and prevention mechanism through information technology, timely notify the construction unit of effective information, establish and improve risk management and supervision mechanisms and The closed-loop mana...

AI Technical Summary

Problems solved by technology

[0003] In conventional surrounding rock measurement and monitoring, there are often the following deficiencies: (1) The current monitoring of tunnels mostly uses displacement measurement methods, including ground subsidence and cave wall displacement measurement. Due to the existence of cracks (voids) and the strong brittleness of the surrounding rock, the displacement before failure is very small, and the results of settlement monitoring often cannot reflect the safety of the tunnel in time and accurately

Although the tunnel wall displacement measurement directly measures the tunnel wall, it measures the displacement at a single point on the tunnel wall, which often cannot reflect the maximum deformation and the overall deformation mode of the tunnel, and the lining is also relatively brittle, and the displacement before failure is small , Disadvantages of high precision requirements for displacement measurement

(2) The traditional surrounding rock measurement adopts the mode of "manual reading, manual filling, and paper report". There are many human intervention factors, slow data processing, information cannot be fed back in time, and reports cannot be summarized in time

(3) The problem of data traceability: it is impossible to form an instant, effective and continuous data chain, which makes it difficult for managers to realize the whole process monitoring, and data distortion and loss are very easy to occur

When it is necessary to consult historical data, it is laborious and difficult to trace

(4) The monitoring data is difficult to share and analyze and utilize: currently, only the front-line information can be collected, sorted out and archived through various construction units

The data are all unstructured documents, which is not conducive to retrieval and statistics. Since there is no unified format, data sharing and post-analysis are difficult
