A method for automatic monitoring and measurement of multi-section tunnels

Abstract

The present invention provides an automatic monitoring and measurement method for multi-section tunnels, comprising: a main control unit sets initial monitoring and measurement parameters; the main control unit controls n monitoring and measuring units to simultaneously monitor and measure parameters according to the set monitoring and measurement frequency and record the measurement data returned by each monitoring and measuring unit in real time; when the automatic monitoring and measurement of the tunnel ends, the vault subsidence change curve and the surrounding displacement data change curve corresponding to each tunnel section are obtained. The advantages are: 1. The present invention can monitor and measure multiple tunnel sections at the same time, and the number of monitored sections is scalable; 2. The method proposed by the present invention is more efficient. The method of the invention can reduce the frequency of monitoring personnel entering and exiting the tunnel, so as to ensure the safety of personnel. 3. The method of the present invention has a high frequency of data collection, and through a large amount of data analysis, it can more accurately reflect the real situation of vault sinking and surrounding displacement, and realize efficient monitoring of tunnels.

Description

An automatic monitoring and measurement method for multi-section tunnels technical field The invention belongs to the technical field of tunnel engineering monitoring, be specifically related to a kind of multi-section tunnel automatic monitoring and measuring method Law. Background technique Tunnel monitoring and measurement is one of the three major elements of new Austrian construction, and tunnel construction is carried out by monitoring and measuring results. Informationized construction maximizes the use of the self-supporting effect of the surrounding rock, so that the tunnel construction is in a dynamic management system. specific Before the construction of the tunnel project, the surrounding rock mass was in a stable in-situ stress environment, and the excavation of the tunnel destroyed the original rock mass. The equilibrium state of in-situ stress, by the self-stabilization of the surrounding rock of the tunnel itself and the support of the supporting str...

Problems solved by technology

Due to the cumbersome operation of the traditional tunnel monitoring and measurement method, the monitoring and measurement work must be followed up in real time during the tunnel construction process, and the layout of the measurement points has a greater impact on the construction process. , the embedded parts in the concrete may be destroyed, resulting in wrong measurement data
