Tunnel monitoring measurement early warning method represented by using tree ring

Abstract

The invention relates to the technical field of a highway tunnel monitoring measurement early warning technology, and particularly discloses a tunnel monitoring measurement early warning method represented by using tree ring. Analysis is made by acquiring monitoring data of different measuring points on the same section of a tunnel; concentric rings for extinguishing different early warning states, which continuously increase, are drawn; a tree ring type monitoring diagram is formed to reflect the characteristic and the variation condition of the monitoring data, so that the variation conditions of the monitoring data and a tunnel safety state can be facilitated through density degree and color variation of the concentric rings for extinguishing different early warning states on the tree ring type monitoring diagram; and thus, the current safety states and the historical records of the monitoring points can be conveniently and intuitively examined, a plurality of measuring points can be displayed on the same diagram according to the respective coordinate positions, the safety state of tunnel construction in a monitoring process can be completely reflected, and timely safety early warning operation can be performed. The method can be widely applied to an information construction process.

Description

technical field [0001] The invention relates to the technical field of road tunnel monitoring, measurement, and early warning, in particular to a method for measuring and early warning of tunnel monitoring quantities represented by tree rings. Background technique [0002] With the development of high-grade highway construction in our country, the scale and number of highway tunnels are increasing. The new Austrian method has been widely used in highway tunnel engineering because of its scientific and advanced design and construction. A core content of the new Austrian construction method is to monitor and measure the stability of the surrounding rock and the mechanical behavior of the support system during the construction process, so as to achieve the purpose of correcting the design and guiding safe construction. [0003] Various types of instruments and tools are used in the tunnel construction process to measure and observe the mechanical behavior of surrounding rock, ...

AI Technical Summary

Problems solved by technology

[0006] The current monitoring measurement data processing and representation method is mainly realized by drawing the time history change curve. This representation method can only display the monitoring data changes of the measuring point on the graph, and cannot display the specific location and safety status of the measuring point. It also cannot intuitively reflect the dual-control indicators, so technicians cannot detect alarms and early warnings in time, and there are certain limitations in the process of digital and information-based construction
